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.)

局部均值分解——LMD
说明： 该方法自适应地将一个复杂的非平稳的多分量信号分解为若干个瞬时频率具有物理意义的乘积函数（Product function,简称PF）之和，其中每一个PF分量由一个包络信号和一个纯调频信号直接求出。包络信号就是该PF分量的瞬时幅值，而PF分量的瞬时频率则可以由纯调频信号直接求出，进一步将所有PF分量的瞬时幅值和瞬时频率组合，便可以得到原始信号的完整的时频分布。(This method adaptively decomposes a complex non-stationary multi-component signal into the sum of several product functions (PF) with physical meanings at instantaneous frequencies, where each PF component consists of an envelope signal and a pure The FM signal is directly obtained. The envelope signal is the instantaneous amplitude of the PF component, and the instantaneous frequency of the PF component can be directly obtained from the pure frequency modulation signal. Further, the instantaneous amplitude of all PF components and the instantaneous frequency are combined to obtain the complete original signal. Time-frequency distribution.)
