School of Science, Jiamusi University, Jiamusi 154007, Heilongjiang, China)Abstract: Based on the analysis of AWG N channel characteristics, an optimal IR - UWB receiver structure is found by studying the receiver structure of ultra-wideband impulse radio signals (IR - UWB) under typical modulation modes. The research focuses on the pulse position modulation, The receiver\'s resistance to distance fading and additive Gaussian white noise under pulse amplitude modulation and binary phase shift keying modulation. Through simulation research and performance analysis of the system, it is concluded that the performance of the receiver based on BPSK modulation is optimal, and the structure is simple and easy to implement. Keywords: additive Gaussian white noise; ultra-wideband impulse radio; receiver Chinese Library Classification Number: TN92 Document Identification Code: A The propagation distance D between the transmitter and the receiver. The time delay τ = DΠ c, c is the speed of light in a vacuum. It is assumed that the receiver and the transmitter are completely synchronized, that is, the receiver knows the value of τ. Through the above analysis and research, the best receiver for AWGN channel consists of two parts: correlator and [4]0 Introduction Ultra-wideband technology is a transmission technology widely used in radar and remote sensing. In 2002, the US FFC officially approved the proposal to apply ultra-wideband technology to civil communications, and designated a frequency band for ultra-wideband wireless communication systems [1]...
