扩频系统，首先随机产生01序列，然后通过扩频，脉冲成型，BPSK调制发送，接收端接收进行解扩解调-The wide frequency system, first stochastically has 01 sequences, then through the wide frequency, the pulse formation, the BPSK modulation transmission, the receiving end receive carries on the despre

此函数用于产生脉冲超宽带系统的训练序列的波形。输出参数有三个：bits--发送的数据,stx--发送的信号,ref--参考信号 发送端调制方式为TH-PAM-The emerging ultra-wideband (UWB) system offers a great potential for high data rate wireless multimedia applications of the home entertainment and industry, as well

对采用双二进制信号脉冲的2电平PAM通信系统进行Monte Carlo仿真。输入二进制序列为{bn},预编码序列为{dn},幅度序列为｛an},相关序列为{cn}。将高斯噪声加到接收序列{bk}上去以形成检验信号的输入，并恢复这个数据。对1万个比特执行这个仿真，并在σ2=0.1,0.5,1时分别测量比特差错概率。用此概率跟无ISI的PAM的BER曲线作对比并进行分析。-Partial-Responsing Signal。
