“…The noise variance N 0 and path delays are assumed to be known to the receiver. For the SUI-3 SISO channel, the total channel gain 2 l=0 E[|hl| 2 ] = 2 l=0 P l is normalized to unity, and the parameters are set accordingly to σ 2 = 0.175, s 2 = 0.36, P 1 = 0.223, P 2 = 0.07 in equation (9), (14). For the MIMO channels, the antenna correlation coefficient defined in (19) ]| 2 = 0.174; P 0 00 + P 1 00 + P 2 00 + P 0 10 + P 1 10 + P 2 10 = 1.0.…”

The systems under investigation are broadband fixed wireless access (BFWA) systems operating in multipath fading channels. Conventional detection methods, e.g., coherent detection for single-input, single-output (SISO) systems and the Alamouti algorithm for multiple-input, multiple-output (MIMO) systems are examined theoretically in this paper and shown to yield unsatisfactory performance. The theoretical analyses are validated by Monte-Carlo simulations and are demonstrated to be accurate. The asymptotic performance of the space-time block coded (STBC) system with the Alamouti transmission scheme is also evaluated. However, the results indicate that the performance lower bound cannot be obtained in an uncoded system due to the error propagation problem, which can be tackled by concatenating the STBC system with an outer channel code and applying the turbo processing principle. The theoretical performance analysis conducted in this paper give us an insight into the physical limitations imposed by the BFWA channels and suggest solutions to improve the capacity and performance of future BFWA systems.

“…Recent advances on the performance analysis of digital communication systems in fading channels has recognized the potential importance of the MGF or Laplace transforms as a powerful tools for simplifying the analysis of diversity communication systems. This led to simple expressions to average bit and symbol error rate for wide variety of digital communication scheme on fading channels including multipath reception with correlated diversity [11,[34][35]. Key to these developments was the transformation of the conditional error rate expressions into different equivalent forms in which the conditional variable appears only as an exponent.…”

Abstract-In this paper, we have analyzed the channel capacity by using the maximal-ratio combing (MRC) diversity scheme for communication systems operating over a composite fading environment modeled by the Generalized-K distribution at the receiver. For the Generalized-K fading channel with arbitrary values for small and large scale fading parameters, we have derived a closed-form expression for the moment generating function (MGF) of the received signal-to-noise ratio (SNR) and utilized it to obtain a novel closed-form expressions for the channel capacity under different adaptive transmission schemes. The result of the proposed methods is compared with other reported literature to support the analysis.

Abstract-The conventional transmit diversity schemes, such as Alamouti scheme, use several radio frequency (RF) chains to transmit signals simultaneously from multiple antennas. In this paper, we propose a low-complexity repetition time-switched (RTSTD) transmit diversity algorithm, which employs only one RF chain as well as a low-complexity switch for transmission. A mathematical model is developed to assess the performance of the proposed scheme. In order to make it applicable for practical applications, we also investigate its joint application with orthogonal frequency division multiplexing (OFDM) and channel coding techniques to combat frequency selective fading.
