[matlab] GMSK_QPSK_8PSK DL : 0: 里面有8PSK，GMSK的matlab源程序，贡献出来了-I was interested in the theory for 8PSK and came across this m-file written in 1999. It requires 2 function calls (graymapPSK and grayunmapPSK) which I have included and must be uncommented(single comments only) and loaded into your workspace. Remove the function calls from this m-file after you load into your workspace. It seems to work well and give valid results for BPSK and QPSK but I have a question about the setup for 8PSK and the solution for Pseint where Pse=Pseint. Also, the Gray coding seems different than what I m used to. Some of you more theoretical minded may have some insight into the theory behind how Pseint was determined and comment. I don t have the communications toolbox-blockset and was wondering how it compared with Matlab s example simulation of 8PSK with Gray coding (in Simulink?) Each run takes about a minute and the loop iterations are shown in the command window. A numerical example of a satellite link is shown using uncoded QPSK

[Communication] ofdmgen.m DL : 0: MATLAB program for OFDM generation and reception This is a simple MCM communications system. The code is pretty self-explanatory. Here I have not used the cyclic prefix. Transmitter End: 1. Generate random serial data with M symbols (RANDSRC will do this) 2. Perform modulation (4-PSK = QPSK for now) 3. Serial to parallel 4. IFFT 5. Parallel to serial Receiver end Just opposite of transmitter end.
