本程序实现了OFDM系统详尽的方针，注释代码非常丰富，有详细的讲解，可以实现AWGN信道和多径信道，并对最终的如BER等性能指标进行了仿真实现。非常经典。很适用发论文或毕业设计时用来做设计的仿真验证工作。(This procedure detailed implementation of the principle of OFDM systems, notes the code is very rich in detail there is, you can achieve AWGN channel and multi-path channel, and the ultimate properties such as target BER simulation implementation. Very classic. Hair is the application of graduation thesis or design Designed to make the job simulation.)

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 )
