Abstract :
In this paper we present a transceiver scheme based on a novel equalizer for indoor DS-UWB systems. The proposed scheme consists of a transmitter, a receiver with a novel equalizer which can reduce the overhead during the training phase and reduce the computation complexity without inducing loss of the BER performance. Furthermore, we evaluate performance on convergence rate, complexity and robustness for adaptive algorithm, and then compare the proposed scheme with the conventional structure under the realistic IEEE 802.15.3a channel model. Simulation results support the theoretical analysis and show that the proposed scheme can achieve higher throughput than a conventional one without loss of BER performance.
