说明： 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.)

平台运行:
基带发端仿真系统\LTE_LTE_main_gui_final.m
在该仿真平台中，分为4种运行模式
第一种模式为载入小区参数（仅发端）。参数配置从题目给定的’小区参数.dat’文件中读取参数。并将题目给的’业务数据.dat’作为发送的信息比特，对其进行基带的处理。
第二种模式为手动配置参数（仅发端）。使用者可通过界面上的提供的选项，为基站的基带处理配置参数。有效参数包括系统公共参数、用户公共参数、用户独立参数以及仿真次数。
第三种模式为仿真BLER曲线（包含发端收端）。使用者除了配置第二种模式的选项外，还可以选择第三列的参数。第三列里的参数选项主要包括接收方式配置、仿真信噪比区间、信道的选择等参数。程序运行结束后，会在右下角的绘图区域显示本次仿真的误块率曲线。
第四种模式为载入已有BLER曲线。因为得到误块率曲线花费的时间很长，使用者可以载入预先仿真好的部分曲线。
[注]：由于gui界面较大，在15英寸显示器上因分辨率较小而无法显示全所有信息。
