摘要：

By considering the feature that the channel is basically unvaried during the course of transmitting many bits data in ultra-wideband (UWB) communications, a novel UWB correlation receiver of the average transmitted-reference type was presented. In transmitting end, every frame is composed of header several reference signals and many modulated data signals. The accumulated average of these received reference signal waves is used by the receiver as the correlation template to demodulate the subsequent data signals. Because the signal-to-noise ratio of the correlation template is increased, the bit error ratio (BER) performance of the receiver is improved while the structure is still kept simple and easy to be realized. The theoretical analysis and simulation of the IEEE multipath channel models show that BER performance of the receiver is obviously superior to the conventional autocorrelation receivers and has about 2 dB signal-to-noise ratio gain at 10-2 BER.
