自己編寫的matlab代碼，實現fft函數及ifft函數功能(I have written matlab code to achieve the original fft function and the ifft function)

自己编的基于霍夫曼编码以及解码的程序，供大家分享(Own compilation based on Huffman coding and decoding procedures for share)

This is a model of a QPSK modulation system for transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC fi lters with excess bandwidth α = 0.18 are employed. The receiver includes an NDA timing recovery loop followed by a DD phase recovery loop. (This is a model of a QPSK modulation system f or transmission over a bandpass channel with fc = 100 Hz and B = 30 Hz and AWGN at the receiver. SRRC)
