2fsk
- 2FSK是利用数字基带信号控制在波的频率来传送信息。经过调制后的2FSK数字信号通过两个频率不同的带通滤波器f1、f2滤出不需要的信号，然后再将这两种经过滤波的信号分别通过包络检波器检波，最后将两种信号同时输入到抽样判决器同时外加抽样脉冲，最后解调出来的信号就是调制前的输入信号。-gudi hduidf hdag sdd w

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
