改进参考信号的差分发送参考UWB自相关接收机
Differential transmitted reference UWB autocorrelation receiver based on modified reference signal
摘要
Abstract
Due to the serious impact of the noise component contained in reference signal on Differential Transmitted Reference (DTR) receiver's performance, the paper proposes the Modified Reference Differentia] Transmitted Reference (MRDTR) autocorrelation receiver for Impulse Radio Ultra-WideBand (IR-UWB) wireless communication systems. This receiver sums up the reference signals in every frame during the previous symbol interval and then averages them to form the new reference signal. The noise effect on the receiver performance is reduced by the average method. Then the received signals in each frame during the current symbol interval are multiplied with trie new reference signal and the products are integrated. These integral results in every frame are summed up and the sum is decided to recover the transmitted symbol. The Bit Error Rate (BER) performance of the receiver is improved by constructing the new reference signal. Its BER performance is analyzed over resoluble multipath channel. Theoretic analysis and simulation results verify that the BER performance of the MRDTR receiver is superior to DTR receiver evidently.关键词
