研究超宽带通信编码优化问题,由于超宽带通信中,发射机和接收机之间受障碍物的阻挡,使得编码信号不能直接传输,而是多径传播到接收机端.传统的Gold编码通过多径传播造成信号的衰落,导致传播误码率较高的问题.提出一种截短平衡Gold码的超宽带通信编码算法,将传统的Gold码截短平衡,采用PAM调制后通过Intel信道传输,将Gold截短增强了信号反射性减少了信号衰减,取平衡码传输降低了传播误码率,避免了传统的Gold码在多径传播中误码率较高的问题.实验证明,编码方法能够提高多径传播的准确率,满足超宽带通信的准确性要求,取得了满意的结果.%Research the ultra - wideband communication code to reduce the communication error rate. In ultra-wideband communications, barriers between the transmitter and receiver make the transmitting of code signals blocked, and code signals are transmitted to the receiver in multipath. The traditional Gold code with multipath propagation causes signal fading, resulting in higher transmission bit error rate. This paper presented a truncated balanced Gold code of ultra - wideband communication coding algorithm, which got the truncated balanced traditional Gold code, ues the PAM modulation and transmitted though Intel channel. The algorithm enhanced the signal and reduced signal attenuation. The balance transfer reduce the bit error rate of the spread code, and avoided the problem of high error rate in traditional Gold code with the multipath propagation. Experiments show that this encoding method can improve the accuracy of multipath propagation, and meet the accuracy requirements of ultra - wideband communications with satisfactory results.
