2007 10th Canadian Workshop on Information Theory (CWIT), 2007

With the technique of random binning, the idea of network coding is extended and applied to multiuser channel coding problems. Specially, a two-way relay channel and a three-way broadcast channel are considered in this paper, and the corresponding achievable rate regions are determined.

We propose a novel scheme for iterative multiuser detection and turbo decoding. The multiuser detector and single-user turbo decoders are coupled such that after each turbo decoding iteration the extrinsic information of the interfering users is passed to the multiuser detector, and after each multiuser iteration, updated a posteriori probabilities are passed to the single-user turbo decoders as the soft ...


On rate region bounds of broadcast relay channels

We also provide an upper bound on the capacity region. For broadcast relay channels with the relay node receiving its own information from the source, we obtain the achievable rate region as well.

The multiuser detector and single-user turbo decoders are coupled such that after each turbo decoding iteration the extrinsic information of the interfering users is passed to the multiuser detector, and after each multiuser iteration, updated a posteriori probabilities are passed to the single-user turbo decoders as the soft input metrics. The proposed detector approaches the multiuser capacity limit within 1 dB in the low signal-to-noise ratio region.

  • SINR-Max cooperative beamforming for multiuser MIMO-OFDM systems

    In our previous works, we proposed an uplink transmit beamforming design algorithm for multiuser multiple-input multiple-output (MIMO) systems in frequency non-selective channels, under the assumption that cooperation exists among multiple users so that the full multiuser channel state information (FMCSI), i.e. the collection of the channel state information between each of the users and the base station, is available at each of the multiple users. The proposed algorithm, aiming to maximize the signal to multiuser interference plus noise ratio (SINR), is referred to as SINR-Max cooperative beamforming. In this paper, we extend the application of SINR-Max cooperative beamforming to frequency selective block invariant channels by combining orthogonal frequency division multiplexing technique into MIMO systems (MIMO- OFDM). We designed two alternative transmitter structures with pre-IDFT beamforming in the frequency domain and post-IDFT beamforming in the time domain respectively, and the receiver structure common to both types of transmitters. For post-IDFT transmitter, we investigated different implementation options. Performance of the designed systems with different schemes is evaluated and compared through simulations.

  • Iterative decoders for multiuser ISI channels

    The goal of this work is to design and analyze the performance of various multiuser coding and iterative decoding methods for intersymbol interference (ISI) networks. The introduction of turbo coding and iterative decoding schemes have changed the coding and detection landscape drastically. However, most of the results are for single-user channels which do not suffer from interchannel interference (ICI). This work extends the performance results for turbo coded schemes by investigating a more general multi-user ISI network. The results show that turbo coded systems provide superior gains to uncoded systems under both deterministic and stochastic ICI cases.

  • Subspace-based channel estimation for wideband CDMA communication systems

    Subspace-based channel estimation for CDMA systems exploits the eigenstructure of the received data matrix, allowing reconstruction of signature waveforms without the knowledge of the input signals. In this context, we consider the estimation of multiuser channels for wideband CDMA systems. By relying on knowledge of the structure of the propagation channel, the proposed channel identification is computationally more efficient. In particular, we reduce the number of unknown parameters in the new channel model by forming a set of spatial parameters and a set of temporal parameters. Simulations are performed to evaluate the algorithm.

  • Throughput maximization and optimal number of active users on the two transmit antenna downlink of a cellular system

    This paper presents an analysis of the sum-capacity of the vector broadcast channel with two transmit antennas and K mobile users equipped with a single antenna. We derive the optimal power allocation on the dual sum-power multiple access channel. We show that in contrast to conventional water-filling, the number of users that are allocated power in order to maximize the mutual information can be a non-monotonic function of the total power for some channel realizations, and it can be larger than the number of transmit antennas. We give a geometrical interpretation of this phenomenon and we show simulation examples. We also show that despite the fact that more users than transmit antennas might need to be allocated with power in order to maximize the mutual information, constraining the number of active users to be no more than the number of transmit antennas incurs only a marginal loss in spectral efficiency both in terms of outage and ergodic capacity.

  • Block Faded Channel Estimation for Multiuser STBC-OFDM Systems

    Accurate channel estimation is necessary to gain the advantage of space time coding for decoding purposes. Most of the previous work on orthogonal frequency division multiplexed (OFDM) channel estimation focused on single user systems. Hence, they are inappropriate in the multiuser communication systems. In this paper, we proposed a novel multiuser channel estimation technique based on simple blocked pilot grid for space time block coded (STBC)-OFDM systems. We simulated the proposed scheme for slowly faded quasi- static channel. LS and MMSE estimator performance for different number of users are also analyzed

  • Capacity Theorems for the “Z” Channel

    We consider the two-user "Z" channel (ZC), where there are two senders and two receivers. One of the senders transmits information to its intended receiver (without interfering with the unintended receiver), while the other sender transmits information to both receivers. The complete characterization of the discrete memoryless ZC remains unknown to date. For the Gaussian ZC, the capacity has only been established for a crossover link gain of 1. In this work, we study both the discrete memoryless ZC and the Gaussian ZC. We first establish achievable rates for the general discrete memoryless ZC. The coding strategy uses rate-splitting and superposition coding at the sender with information for both receivers. At the receivers, we use joint decoding. We then specialize the rates obtained to two different types of degraded discrete memoryless ZCs and also derive respective outer bounds to their capacity regions. We show that as long as a certain condition is satisfied, the achievable rate region is the capacity region for one type of degraded discrete memoryless ZC. The results are then extended to the two-user Gaussian ZC with different crossover link gains. We determine an outer bound to the capacity region of the Gaussian ZC with strong crossover link gain and establish the capacity region for moderately strong crossover link gain
