| 摘 要： | 脉冲超宽带(IR-UWB)信号在密集多径环境中存在严重的时间弥散,会产生波形失真.针对BPSK调制的UWB通信系统,分析了在加性高斯白噪声(AWGN)密集多径衰落信道下,利用改进的Hermite基波合成波形作为模板的等增益合并部分RAKE(PRAKE)接收机的误码率性能.仿真结果表明了其有效性.

| Abstract: | In dense multipath environments, IR-UWB (Impulse Radio-Ultra Wideband) signals suffer from severe time dispersion which distorts the impulse wave. With the assumption of that BPSK modulation is used, this paper analyzes the BER performance of EGC (equal-gain combination) PRAKE (partial RAKE) receivers based on a synthesized template using several modified Hermite elementary waveforms in AWGN and multipath fading channels. |
