|Abstract:||Impulse radio (IR) is based on Ultra-wideband time-hopping spread spectrum technique in which sub-nanosecond of pulses are modulated to convey information by shifting the relative time position of the pulses. In this paper, the influence of temporal and spatial diversities is analyzed on the performance of ultra-wideband impulse radio systems. We investigate how antenna diversity (uniform linear array and rectangular array) can be used to improve the bit error rate (BER) performance of the IR systems in dense multipath environments. Analytical and simulation results show that the BER performance of the IR system can be improved when the number of array elements is increased. The performance can be further improved by coherently adding more number of multipaths at the receiver.|
