ZHAO_OFDM
这个程序除了接收机同步、信道编码没有加入外，基本上反映了一个OFDM系统的特性：
1. qpsk/16qam/64qam映射、解映射
2. OFDM调制解调（循环前缀，FFT等）
3. 非整数采样时刻多径时延的多径信道
4. Rayleigh或者Rician多径信道
5. 信道的连续时变（非block fading）
6. 线性插值信道估计
7. FFT变换域插值信道估计(In addition to this program receiver synchronization, channel coding have not joined, the basically reflect the characteristics of an OFDM system: 1. Qpsk/16qam/64qam mapping, mapping solution 2. OFDM modulation and demodulation (cyclic prefix, FFT, etc.) 3. Non- integer sampling instant multi-path delay of multi-path channel 4. Rayleigh or Rician multipath channel 5. a continuous time-varying channel (non-block fading) 6. linear interpolation channel estimation 7. FFT transform domain interpolation channel estimation)

Abstract—In this paper, we study the joint estimation of inphase
and quadrature-phase (I/Q) imbalance, carrier frequency
offset (CFO), and channel response for multiple-input multipleoutput
(MIMO) orthogonal frequency division multiplexing
(OFDM) systems using training sequences. A new concept called
channel residual energy (CRE) is introduced. We show that by
minimizing the CRE, we can jointly estimate the I/Q imbalance
and CFO without knowing the channel response. The proposed
method needs only one OFDM block for training and the training
symbols can be arbitrary. Moreover when the training block
consists of two repeated sequences, a low complexity two-step
approach is proposed to solve the joint estimation problem.
Simulation results show that the mean-squared error (MSE) of
the proposed method is close to the Cramer-Rao bound (CRB).
Index Terms—MIMO OFDM, CFO, I/Q imbalance, channel
estimation.

BER
这是一个matlab和optisystem联合调试用的误码率计算程序，里面的文件报过一个可以用optisystem7和optisystem13可以打开的OSD仿真图，还有一个MATLAB计算BER的程序。给出了如何设置系统的大纲。从OptiSystem的电信号输入到Matlab组件。当OptiSystem运行时，它将调用Matlab组件中的M文件，处理数据，然后将所得的电信号导出回OptiSystem。然后将输出信号连接到BER分析仪。经过我调试，文件齐全，放心下载(The attached image gives an outline of how the system should be setup. You should start with inputting the electrical signal from OptiSystem into a Matlab component. When OptiSystem runs, it will call the M-file in the Matlab component, process the data, and then export the resulting electrical signal back into OptiSystem.The output signal is then connected to the BER Analyzer.)
