An OFDMA system is considered in which minimum allocation unit is one Physical Resource Block (PRB) containing 12 sub-carriers in each TTI of 1 ms duration.

编码、传输、存储和译码是语音数字传输和数字存储的必要过程。 随着语音通信技术的发展，压缩语音信号的传输带宽，增加信道的传输速率，一直是人们追求的目标。语音编码在实现这一目标的过程中担当重要的角色。 语音编码就是使表达语音信号的比特数目最小。-Coding, transmission, storage and decoding the digital voice transmission and process necessary for digital storage. With voi

本程序利用MATLAB对信号进行分析和处理，主要就是进行语音线性预测通过使实际语音抽样值与线性预测抽样值的均方误差达到最小，可以确定唯一的一组线性预测系数。-This procedure using MATLAB for signal analysis and processing, mainly for voice linear prediction by the actual voice sampling error of the mean square value and the mini
