Hi Friends
How Can calculate SNR for 1/2(code rate) 32APSK,1/3 32APSK, 1/4 32APSK, 1/6 32APSK and 1/2 8PSK that turbo code have been used in LEO Satellite?
SNR computation for APSK is not as clearly defined as the QPSK or the QAM. depending on the distance between symbols required you can use euclidean geometry to arrive at a the final theoretical bound. APSK is custom defined depending on required performance requirement. It is typical european communication tech. you can find some information on DVBS2 or later standards.
