How to demodulate the received data using QPSK (in Matlab)?

[yingmu]

Hi all,

Anyone has any idea how to demodulate the received data using QPSK (in matlab) if a vector signal generator (VSG) is used to generate data using QPSK?
Thank you.

demodulation qpsk

you can use demod function in Matlab with 'pm' option if your data is available in Matlab workspace. For further info look at the documentation available on 'demod' function.

Re: QPSK demodulation

but there isn't any parameters that I can set to tell matlab my signal is a qpsk signal..'pm' is a general case? Thank you
