SpectatorHELLO EVERYONE..
I have to design a MSK receiver ie. by using dual polarization technique but there is need for MSK sequence decoder to combine the in phase and out of phase components in electrical domain. is no readHowever there is no such block..
Can someone help how do design it..Regards

ParticipantHi Fayiqa,
You find “PSK sequence decoder” in optisytem software.
Steps as follows:
default- receivers library- decoder and then we will have PSK sequence decoder.
we could use this decoder in Dqpsk system.
In the DQPSK system receiver you will get some excellent results but not in case of MSK and I noticed that in one of the post damian mentioned that in case of MSK signal it is a bit complex equation to design an exact MSK transmitted signal.
the efficient receiver
for the SC-MSK is to iterate the inner MSK demodulation
and the outer CC decoding, exchanging extrinsic
information between these two soft-input soft-output
(SISO) modules.Here i am posting you link which help you.

SpectatorHI RAJGURU..
Thank you for your efforts..There are already many papers which suggest use of MSK receivers instead of PSK receivers.Regards
