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
