rand, randn, randint.... you can understand my code

产生一正态分布序列 经过pcm编码、PCM解码、计算量化信噪比、设置信道误码率 -Generating a normal sequence after pcm encoding, PCM decoding, computing quantization noise ratio, set the channel error rate x = randn (1,1000) generating a normal sequence xf = fft (x, 256) 1024 da

在matlab中无论是wgn还是awgn函数，实质都是由randn函数产生的噪声。即：wgn函数中调用了randn函数，而awgn函数中调用了wgn函数。(The principle of AWGN adding white noise)
