| 摘 要： | 分析比较了3种基于自相关接收原理的超宽带发送参考(TR)冲击无线电系统,即简单TR(STR)系统、平均TR(ATR)系统和差分TR(DTR)系统在多径信道中的误码率(BER)性能、实现复杂度和传输速率,并时这3种系统的性能在CMI和CM2信道中进行了计算机仿真.分析和仿真结果表明,ATR和DTR的性能恒优于STR,但ATR和DTR的性能的优劣则取决于具体的参数取值,在一定的参数条件和复杂度约束下,DTR系统是一种在性能、复杂度和传榆速率方面都能兼顾的比较折中的传输方案.

| Abstract: | This paper analyses and compares the bit error rate(BER) performance,transmission rate and complexity of three ultra-wideband transmitted reference(TR) systems based on autocorrelation receiver: simple TR(STR) system,average TR(ATR) system and differential TR(DTR) system in the multi-path channel,respectively.Analysis and computer simulation results in the scenario CM1 and CM2 show that the performances of ATR and DTR are constantly better than that of STR and that whichever of ATR and DTR systems is better... |
