Abstract

A novel system based on cooperative distributed space-time block code (DSTBC)and multi-band orthogonal frequency division multiple (MB-OFDM) is proposed which works well on multiple single-antenna users wireless networks in ultra-wideband system. In this system, using MB-OFDM technology modulate data to subcarriers, can resist the influence of frequency selective fading channel effectively. Over cooperative diversity scheme based on DSTBC-MB-OFDM, a theoretical bit error rate (BER) performance expression of the system has been derived. Also its closed-form expression is derived by means of the moment generating function (MGF). Monte Carlo simulation results are given to demonstrate the BER performance of DSTBC-MB-OFDM outgoes non-cooperative MB-OFDM with distinctive gains.
