Recent advances of DSP, microprocessor (MPU), micro-electronics and the antenna in miniature, makes it possible to employ smart antennas (SA) in a mobile station (MS) in next generation mobile communications (3G). Because the processing capacity of MS is relatively weak, to guarantee the smart antenna performance, its algorithm complexity of the smart antenna is very important. In the paper, we propose a low complex algorithm using the auxiliary pilot signals to estimate the channel parameter in the downlink. Via simulation, we evaluate the performance of SA with two elements in terms of the bit error rate (BER). The simulation results show that using SA can improve the performance of the MS significantly.
Millimeter wave (mm-wave) bands are becoming potentially attractive candidates for next generation communication systems. It is envisioned that high gain smart antennas will be one of the key enabling technologies for such systems. At mm-wave bands, where electrical size of an individual antenna becomes very small, the inclusion of a reconfigurable mechanism in the antenna becomes a great challenge due to real estate constraints. In these scenarios a designer has to decide on the number of bits in a phase shifter for antenna beam steering which will result in an optimum design. This contribution addresses the issue of phase quantization in mm-wave high gain reflectarray smart antennas to achieve an optimum performance. Implementing coarse phase quantization greatly reduces the complexity at mm-wave bands. A case study is presented to highlight the effects of coarse phase quantization using various numbers of bits.
Recently, many studies in wireless ad hoc networks assume the use of smart antennas which can electronically control their beam pattern. Communications using smart antennas can be expected to improve spatial utilization efficiency and to extend communication distance. However, there are some unique problems caused by the use of the smart antennas. In this paper, we focus on the directional hidden terminal and the deafness problems. We propose a directional monitoring scheme and a switching backoff scheme for overcoming these problems. The directional monitoring scheme can solve the directional hidden terminal problem by monitoring the direction toward the destination after sending a data packet. The switching backoff scheme can reduce deafness loss time by keeping backoff-interval as long as the terminal is deaf. Comparing the proposed scheme with conventional schemes by computer simulations, the results show that the proposed scheme can mitigate the effect of these problems and it achieves higher throughput.
Data broadcasting has emerged as an efficient way of delivering information over asymmetric wireless environments. Push systems are able to provide high scalability and client hardware simplicity in such environments. This paper proposes the use of multiple smart antennas to increase the performance of an adaptive wireless push system in environments characterized by locality of demand. Simulation results reveal that the use of smart antennas suffices a significant performance increase over the use of static directional antennas. This is achieved because of the ability of smart antennas to alter their beamwidth and thus, to succeed an efficient coverage of the area where they broadcast.
In wireless communication, the broadcast server serves numerous clients. The exchange of information from server and access by the clients takes place in a cyclic path using the directional antennas. But directional antennas have several drawbacks. So the multiple directional antennas were used to replace the fixed directional antenna systems. When using the multiple antennas to get the desired improved performance, we need to consider the geographical distribution of all the clients present in the coverage area of system. All these disadvantages motivate us to develop a technique named as a wireless push system developed using adaptive smart antenna with rescheduling application to be used at broadcasting server. Smart antennas can vary the beam widths according to client position using suitable algorithms. Beam width of the antenna is changed as per the changing position of the client and appropriate changes are introduced in the broadcasting schedules. This approach will bring the desired improvement in system performance.
In this paper, we conducted a comparison study of the existing directional MAC protocols that use Smart Antennas by contrasting their features. We found that, most of these protocols are not applicable in mobile environment This investigation discusses the challenges in improving some of these smart antenna-based MAC protocols. We proposed to upgrade two protocols, Tone-DMAC protocol and Angular-MAC protocol. We proposed to model the behavior of these two protocols analytically and carry the improvement performance by using two omni-directional control packets. We suggested that using these two packets and Adaptive Array Antennas in the above protocols will make them applicable in mobile environment and as well as improve routing performance.
Smart antennas are important for SATCOM on-the-move (SOTM) because they can increase the channel capacity and coverage range of the communication systems. Firstly, this paper briefly reviews the state-of-art on the smart antenna design for SOTM applications. Different types of antenna for SOTM are discussed. Then, two design examples from the recent collaborated research work from the University of Kent are presented. One is a Ka-band low-cost beam scanning folded reflectarray. This reflectarray uses the dual-polarized slot antenna with multi-layered PCB structure as the unit cell and scans its beam within large angle range. Another design example is a Ku-band low cost dual polarized reconfigurable reflectarray with single bit phase control by using PIN diodes. For both design examples, measurement results are given to show their good beam scanning performance.
This work establishes a state-of-the-art protective measure on how the smart antennas can be used effectively to curtail the activities of hackers/intruders on radio frequency signals. Hackers can scan confidential information/data belonging to organization, law enforcement and even interception of radio frequencies signals to the public usage. In this analysis, three antenna elements array have been used. (i) The first antenna elements was used for the transmission/reception (transceiver) of radio frequency signal. This transceiver also acts for remotely transmitting information signal virtual to mobile station. (ii) The two antenna elements at the mobile station is being used as descrambler against any illegitimate activities. Some of the imperative securities challenges covered in this work are secrecy, authentication, privacy, and attacks. In the choice of frequency bandwidth for the transmission of signal, IEEE standard 802.11 designed for wireless local area network system had been maintained.
Firstly a downlink transmission model which includes smart antennas is developed. Based on this model, the TD-SCDMA downlink transmission beamforming methods, in consideration of a mobile terminal using various data detection algorithms (joint detection, single detection), are discussed respectively. Three beamforming methods have been evaluated and two of them have been modified in order to make them available for the TD-SCDMA systems. Furthermore, the data detection methods have been investigated under the influence of these beamforming methods.
