This Telecommunication Standard [TS] describes the detailed mapping from input blocks of 160 speech samples in
13-bit uniform PCM format to encoded blocks of 95, 103, 118, 134, 148, 159, 204, and 244 bits and from encoded
blocks of 95, 103, 118, 134, 148, 159, 204, and 244 bits to output blocks of 160 reconstructed speech samples

function [sampl,re_sampl]=system_1(A,F,P,D,snr,m,N)
輸入變量A ,F,P分別為輸入信號的幅度、頻率和相位，D為量化電平數(shù)，snr
為信道信噪比，N為D/A轉換時的內(nèi)插點數(shù)；輸出變量sampl為抽樣后的輸入
信號，re_sampl為恢復出的輸入信號。
