| 摘 要： | 对工作在多径有噪信道内的DS-BPSK超宽带通信系统进行分析,得到了扩频码正交性保持情况下系统信道容量的理论公式,并根据分析结果进行了Matlab仿真。仿真结果显示,该理论公式能较好地反映影响DS-BPSK超宽带通信系统信道容量的各种因素。

| Abstract: | A formula for the channel capacity of DS-BPSK UWB system over multipath AWGN channel is proposed in case that the orthogonal codes are kept.Both theoretical analysis and numerical simulation indicate that most of the factors affecting the performance of DS-BPSK UWB communication system can be revealed by using the proposed formula,which demonstrates the effectiveness of our formula. |
