Description: 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
