| 摘 要： | 为了解决跳时超宽带中跳时序列数目的不足,提出将Reed-Solomon码用于跳时超宽带的跳时序列,并在传送端引入预滤波的技术方案。该方案不仅可以增加跳时超宽带中跳时序列的选择,而且可以对传输信道进行预滤波,从而提高系统的整体性能和系统容量。采用IEEE802.15.3a标准信道模型,仿真了在理想RAKE接收机情况下的系统误码率和系统容量。仿真结果表明:在多用户情况下,该方法产生的跳时序列比传统跳时码序列更有效地减少了用户之间的干扰,降低了系统误码率,增加了系统容量。

| Abstract: | We present a UWB system which uses Reed-Solomon codes as time-hopping codes and add pre-filter in the transmitter to solve the lack of the number of time-hopping codes.The method can not only add the number of time-hopping code,but also get enhanced system performance and system capacity by means of signal pre-filtering at the transmitter.By appling the IEEE 802.15.3a channel model,the system RBE and capacity were simulated under the ideal RAKE receiver.The simulation results show that RS time-hopping codes presented in the paper had a lower MUI interference and a lower bit error ratio and got enhanced system capacity over traditional time-hopping codes. |
