In this paper, we present and analyze efficient frame synchronization and frequency offset compensation scheme with ternary sequences for an orthogonal frequency division multiplexing (OFDM) system in Rayleigh fading channels. Frame synchronization is an essential procedure for normal operation of the OFDM system because of sensitivity to synchronization errors. And when there are frequency offsets in OFDM frame, the loss of orthogonality occurs and the interference problem among several subcarriers is introduced. These fact leads to the requirement for joint implementation of the frame synchronization and frequency offset compensation.

该程序能够较好的仿真出Missive MIMO系统下 信道估计的误码率，及还 有部分的MSE代码，可以供大家参考一下！(This program can better simulate the error rate of channel estimation under Missive MIMO system, and also There are some MSE code that you can refer to!)
