本代码主要运用MATLAB的simulink的模块构建了一个OFDM的基本链路，并研究了AWGN信道在不同SNR下产生的误码率(BER).(This code mainly uses the MATLAB module of Simulink to build a basic link of OFDM, and studies the error rate (BER) of AWGN channel under different SNR)

matlab冈萨雷斯答案： 里面是最全的答案，所有习题都有(Gonzalez matlab answer: it is the whole answer, all exercises are)

u can calculate DCT clc inp = imread( Im1.jpg ) inp1 = imread( Im2.jpg ) A = double(inp(:,:,1)) B = double(inp1(:,:,1)) A1=double(blkproc(A,[8 8], dct2 )) B1=double(blkproc(B,[8 8], dct2 )) [r,c] = size(A1) r1 = [] for i=1:r for j=1:c if A1(i,j) > B1(i,j) r1(i,j)=A1(i,j) else r1(i,j)=B1(i,j) end end end r1= double(r1(:,:,1)) C=blkproc(r1,[8 8], idct2 ) round(C) C1=idct2(r1) figure imshow(uint8(C)) figure imshow(uint8(C1)) imwrite(uint8(C), dct8x8min.jpg )

改进后的游程编码，可以继续量化编码转化为二进制数据流，针对一些较为接近的数，通过合适的阈值设定可以近似，从而大大压缩数据流(The improved run-length coding, can continue to quantify the code into binary data stream, for some of the more close to the number set by appropriate threshold can be approximated, thereby greatly compressed data stream)
