pipelined_fft_128_latest.tar
- CFFT是一个数据宽度和点数都可配置的基4 FFT core，由于旋转因子是用CORDIC算法实现的，因此经过FFT后信号的增益和标准的FFT算法不同。但对于OFDM调制、解调等应用并不重要。由于增益是确定的，因此在输出时乘以确定常数即可等价标准的FFT。该FFT core的输入是正序的，输出是按照基4反序的-CFFT is a data width and number can be configured based 4 FFT core, due to the rotation factor

- 接收端采用的算法和程序流程与发送端发送的OFDM符号的帧结构有关系。具体的帧结构，以及定时估计，频偏估计，剩余误差跟踪的算法可参考算法说明文档。这里对程序的流程进行说明。 首先根据短训练字的特性进行相关运算，进行信号到达检测，当检测到相关值大于门限一定次数后，认为有信号到达。然后根据长训练字的特性，进行相关运算，进行OFDM符号FFT窗口起始位置的估计。估计出FFT窗口的位置后，先在时域进行小频偏的估计，将两个长训练字进行小频偏补偿后，进行FFT运算，根据FFT运算的结果进行整数倍频偏的估计
