用simulink中s函数实现两路切换开关(S function with simulink realization of two-way switch)

说明：  在瑞利信道中，对于OFDM信号设计一种具体的导引辅助的信道估计方法，用Simulink进行仿真，测量BPSK调制时的误码率性能。画出比特信噪比与信道估计均方误差的关系曲线，画出比特信噪比与误码率的关系曲线(In Rayleigh channel, a specific guidance aided channel estimation method is designed for OFDM signal, and the simulation is carried out with Simulink to measure the BER performance of BPSK modulation. The relation curve between bit SNR and channel estimation mean square error is drawn, and the relation curve between bit SNR and bit error rate is drawn)

基于梳状导频图案的OFDM系统估计，采用LS信道估计方法，和线性插值法，信道采用瑞丽多径信道。(The OFDM system based on comb pilot pattern estimation adopts LS channel estimation method and linear interpolation method, and the channel adopts the Ruili multipath channel.)

这是一个相对完整的OFDM通信系统的仿真设计，包括编码，调制，IFFT， 上下变频，高斯信道建模，FFT，PAPR抑制，各种同步，解调和解码等模 块，并统括系统性能的仿真验证了系统设计的可靠性 (OFDM full version of the source code, including coding, modulation, IFFT, Upper and lower frequency, Gaussian channel model, FFT, PAPR suppression, a variety of synchronization, demodulation and decoding module, and system performance of the omnibus simulation verify the reliability of the system design)

TD-LTE下行传输采用了MIMO-OFDM的物理层构架，通过最多4个发射天线并行传输多个（最多4个）数据流，能够有效地提高峰值传输速率。LTE的物理层处理过程中，预编码是其核心功能模块，物理下行共享信道的几种主要传输模式都是通过预编码实现的。(The td-scdma LTE downlink transmission adopted MIMO - OFDM frame, the physical transmission antennas parallel transmission by up to four more (up to 4) data flow, can effectively improve the peak transmission rate.LTE) in the process of the physical layer of precoding is its core function module, several kinds of main physical downlink Shared channel transmission model is achieved by precoding.)

该函数能完成多视图的三维重建工作，牵涉很多三维重建工作的函数，相信一定会对你有用(The file includes 3d reconstruction code)

根据深圳市出租车GPS数据所提供的信息，针对交通出行数据的空间分布特征，选取了4月18号这天的全天数据出租车载客后的行驶数据， 利用mtalab对数据的处理，筛选出出租车的起始点及拥堵的时段的行驶数据并通过kmeans聚类分析设定拥堵的标准，得到对于出租车在路段上的车速在小于2.15公里/小时的时候可以认为非常拥堵，拥堵的时段 5:00-7:00,12:00-14:00,19:00-21:00，非常拥堵的时间段为5:00-7:00，19:00-21:00。(analyse traffic jam status of the shenzhen city)
