| 摘 要： | 将多接收天线应用于跳时(TH)二进制反极性脉冲幅度调制(2PAM)超宽带(UWB)系统中,在存在多用户干扰的环境下以提高系统的误码性能,进而达到高速率通信。分析了在SGA条件下,基于空间分集的SINR的表达式,估计了系统的误比特率,并对2PAM-TH-UWB系统的性能进行仿真。仿真结果表明,随着接收端接收天线数的增加,2PAM-TH-UWB系统误码性能提高。

| Abstract: | Multiple receive antennas are applied to the multi-user binary pulse amplitude modulation（2PAM）time hopping（TH）ultra-wideband（UWB）system so that the BER performance of the system could be improved in the presence of the multi-user interferences and high-data-rate communications could be achieved.On the condition of SGA,the expression for the SINR based on spatial combining is analyzed,the bit error rate（BER）performance is evaluated and the performance simulation of 2PAM-TH-UWB system is carried out.Numerical results show that the BER performance can be enhanced by spatial diversity combining. |
