In this paper, we propose an efficient antenna selection algorithm for wireless MIMO systems with low computational complexity especially when calculating the channel capacity. Our method achieves similar capacity as that of the G-circles algorithm, which is a little lower than that of the optimal antenna selection technique. Simulation results demonstrate that the proposed antenna selection algorithm...
An analysis of an asynchronous DS-BPSK UWB system is presented. The standard UWB channel (proposed by IEEE 802.15.3a task group) rather than AWGN or any other kinds of multipath fading channels by Bo Hu (2004) is employed in the analysis to reflect the actual channel conditions. We adopt the standard Gaussian approximation in the analysis because of its facilities in analyzing the complicated multipath...
Performance evaluations of an asynchronous DS-BPSK UWB system in standard UWB channels by means of characteristic function (CF) method, standard Gaussian approximation (SGA) and simplified improved Gaussian approximation (SIGA) are presented. The standard UWB channel (proposed by IEEE 802.15.3a task group) is employed in the analysis to reflect the actual channel conditions. Firstly, a bit error rate...
