m 7-15.m
%例程7－15 PCM编码
%首先，A律13折线量化的Matlab程序实现如下：
function y=pcmA13(x)
%A律13折线压缩特性
x=x/max(x); % x归一化
z=sign(x); %语音信号是双极性信号，负方向对称
x=abs(x);

%修正相移
switch rx.combining_type
case 'MRC'%对收到的原始信号,不需要修正相移,这个过程在两个信号合并时就进行了

txt 说明.txt
必须有hdl.var和cds.lib。
LDV4，要手工写vcd_trace
LDV5能够自动添加所有端口和信号，但信号或端口在声明时应有字符串参数作为名字，否则ncsc会用默认的名字signalxxx或portxxx，无法识别。
