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)
