In this article,a novel transmit-reference(TR) signaling scheme is proposed for ultra-wideband(UWB) system,where by invoking m-sequence codes the reference and data pulses can be transmitted side by side to increase the data rate.This structure enables demodulation with a simple and practical autocorrelation receiver despite existence of severe inter-pulse interference(IPI).To evaluate detection performance of the new designs,closed-form expression for bit error probability(BRP) is theoretically derived and simulation results confirm the analytical results.In addition,the proposed scheme can be extended to M-ary systems to further improve the data rate and power efficiency.
