Analytical BER Calculation of TAS/MRC-Based Two Hop UWB Communication System Over IEEE 802.15.4a Channel

摘要

In this paper, we calculate the bit error rate (BER) of the orthogonal binary signals in the two hop ultra-wideband (UWB) communication system with the transmit antenna selection scheme at the source and the relay terminals. In the two hop UWB system, relay is configured to perform the decode and forward cooperative strategy. In order to calculate the BER of the investigated UWB system, we consider the characteristic function- based approach to model the sum of path gains of the IEEE 802.15.4a channel. We assume that all the IEEE 802.15.4a channel links are independent and identically distributed and perfect channel state information is available at the transmitter. The results exhibit that the derived BER is a good match with the simulations and it has been significantly improved over the BER of the conventional UWB systems.
