Linear matrix modulators from group representation theory

Proceedings 2003 IEEE Information Theory Workshop (Cat. No.03EX674), 2003

Maximizing the mutual information of high rate linear matrix modulation schemes for MIMO channels is considered. Linear matrix modulators are described in terms of a space-time basis, which is a three-index object, one index for the symbol, one for time and one for transmit antennas. Corresponding to these, there are three kinds of transformations that leave mutual information invariant; orthogonal ...


Asymptotic performance of space-frequency codes over broadband channels

IEEE Communications Letters, 2002

We show that when the number of receive antennas is large, the Euclidean distance among codewords dominates the performance of space-frequency codes, the same result as for space-time codes. Therefore, in the presence of a large number of receive antennas, space-frequency codes can be optimized by using the Euclidean-distance criterion valid for additive white Gaussian noise channels. Simulation results show ...

  • Linear matrix modulators from group representation theory

    Maximizing the mutual information of high rate linear matrix modulation schemes for MIMO channels is considered. Linear matrix modulators are described in terms of a space-time basis, which is a three-index object, one index for the symbol, one for time and one for transmit antennas. Corresponding to these, there are three kinds of transformations that leave mutual information invariant; orthogonal symbol rotations, unitary time and unitary antenna rotations. If a group structure is required of the parts of these transformations that embed into the other, the space-time basis is a set of Clebsch-Gordan coefficients realizing the equivalence of representations of this group, and the space-time basis is an extremum of second-order mutual information. Thus, maximal mutual information matrix modulators may be found using the well developed theory of group representations. As an example, symbol rate 1.5 schemes for four transmit antennas, extending over four channel uses, are considered.

  • Asymptotic performance of space-frequency codes over broadband channels

    We show that when the number of receive antennas is large, the Euclidean distance among codewords dominates the performance of space-frequency codes, the same result as for space-time codes. Therefore, in the presence of a large number of receive antennas, space-frequency codes can be optimized by using the Euclidean-distance criterion valid for additive white Gaussian noise channels. Simulation results show that this conclusion is also valid when the number of antennas is small.

  • Two dimensional spreading codes for the downlink in a multiuser system with multiple antennas

    We present a novel space-time spreading scheme for the down-link in a multiuser system. The primary goals of this work are to increase bandwidth efficiency, and to provide joint multiuser detection and space-time decoding, in each mobile station. Each receiver just needs to know its own spreading code and no information about the channel is required in the transmitter. In the proposed architecture, to achieve high bandwidth efficiency, the number of user-channels, is maximized by taking advantage of the large potential capacity of a multiple antenna system.

  • Simplified BER analysis of rate-compatible punctured convolutional coded cooperative system over slow Rayleigh fading channel

    In this work, we study the performance of rate-compatible punctured convolutional (RCPC) coded cooperation system. Theoretical bit error probability is deduced over slow Rayleigh fading channel based on the characteristics of RCPC codes and coded cooperation. The coded cooperative system obtains two inherent benefits, such as achieving the spatial diversity offered by the relay channel and also the coding advantages provided by the RCPC codes and coded cooperative system. Performance improvement of the coded cooperative system is also provided at last, compared with amplify-and-forward scheme and non-cooperative scheme.

  • A space time code for DS-SS

    As a joint design of coding, modulation and transmit diversity for flat Rayleigh fading channels, space-time code modulation can obtain both diversity gain and coding gain. This paper describes a new trellis code more fit for DS- SS (direct sequence spread spectra) communication systems, as well as the approach to construct it. We can find the optimal space-time code through systematic code search by computer; also we can construct them with optimal distance convolutional code. The space-time code proposed here can get maximal diversity gain and coding gain in a DS-SS system. The simulation results indicate that it outperforms other known codes in a DS-SS system.

  • Space-time-frequency (STF) coding for MIMO-OFDM systems

    We consider the capacity of multiple-input-multiple-output (MIMO) systems that use OFDM as the modulation format. We point out a basic equivalence between antennas and OFDM-tones. This similarity immediately allows us to essentially reuse all space-time codes designed for flat-fading channels in MIMO-OFDM systems operating in frequency-selective channels. An optimum code would thus code across all antennas and tones (as well as time) simultaneously. Since this can become very complex, we propose a method for grouping antennas and codes in such a way that the inherent diversity is retained, while the complexity is greatly reduced. Capacity computations between the full- complexity and the reduced-complexity systems illustrate this tradeoff.

  • Effect of spatio-temporal channel correlation on the performance of space-time codes

    The determinant and rank criteria used for space-time code design apply at high SNR. Code design metrics developed for low SNR assume a channel autocorrelation matrix with equal eigenvalues, which does not hold in many practical scenarios. This paper shows that a space-time code designed to ensure full diversity at high SNR can suffer significant degradation when implemented at low-to-medium SNR because of the channel autocorrelation profile. We examine the effect of the channel autocorrelation matrix on a space-time code's performance and discuss how knowledge of this matrix can be used for code design, particularly from the aspect of space-time trellis code minimum memory requirements. Our discussion applies to both flat-fading and frequency-selective channels that are treated in a unified manner.

  • Distributed space-time code designs via Cayley transform

    Distributed space-time coding achieves full diversity in wireless relay networks without channel information at the relays. This paper is on the design of specific distributed space-time codes. By Cayley transform, the design of unitary matrices is transformed to that of Hermitian matrices. Gradient-descent method is used in the optimization to find codes that are ¿close¿ to orthogonal designs, which is known to be optimal in both coding gain and diversity. The proposed code design method can be used for networks with any relays and transmission rate. The optimized codes are adaptive to the information symbol constellation. Simulation shows that the designed codes achieve full diversity, and outperform the random code and other existing distributed space-time codes.

  • Low complexity iterative receiver for non-orthogonal space-time block code with channel coding

    In this paper, we study the association of nonorthogonal space-time block coding (NO-STBC) with channel coding and propose an efficient iterative receiver. For two transmit antennas, the use of the Alamouti scheme as STBC is optimal owing to its orthogonality and its unitary rate. For more than two antennas, full rate is maintained by giving up the orthogonality. This nonorthogonality makes the decoding often complex and sub-optimal in terms of exploitation of the diversity. In this paper, we present a low complexity receiver based on iterative process performing jointly space-time decoding and channel decoding. Simulations over uncorrelated Rayleigh flat fading channels show that such a receiver exploits at best the space-time diversity provided by the nonorthogonal STBC and the channel coding.
