参考3GPP相关标准并根据LTE技术特征和关键特性，对下行链路级进行设计，包含以下步骤：比特生成、CRC校验、码块分割、编码、速率匹配、码块级联、加扰、调制、层映射、预编码、资源映射、OFDM符号生成和天线映射。为模拟无线传输信道，还需仿真相应的信道模型。收端则是发端的严格逆过程，对接收信号进行一系列处理，得到代表原始发送的信息并判决。(References 3GPP LTE technology standards and in accordance with characteristics and key characteristics of the downlink stage design, comprising the steps of: generating bits, CRC checksum, code block segmentation, encoding, rate matching, code block concatenation, scrambling, modulation , layer mapping, precoding, resource mapping, OFDM symbol generation and antenna mapping. Analog wireless transmission channel, the need to emulate the corresponding channel model. The receiving end is the inverse of the originator of the rigorous, a series of processing the received signal, the representation of the original transmitted information and judgment.)

比较两个不同的倒频谱分析方法cepstrum_computation
比较两个不同的倒频谱分析方法的一个有限的时间框架的言论,即基于fft算法的传统方法(与框架展开复杂的倒频谱),和一个分析方法基于求解有限阶分子多项式的根的倒频谱和直接计算多项式根的位置。(This MATLAB exercise compares two different methods of cepstrum analysis of a finite duration frame of speech, namely the conventional method based on FFTs (with frame unwrapping for the complex cepstrum), and an analytical method based on solving for the roots of a finite order numerator polynomial and directly computing the cepstrum the locations of the polynomial roots.)
