i have the same problem with holly :
??? Error: File: graymapPSK.m Line: 8 Column: 17
The expression to the left of the equals sign is not a valid target for an assignment.
Error in ==> MPSK at 49
symbols = graymapPSK(bits); % gray code map to symbols
i want the graymapPSK function
can anyone help me to find Matlab codes for simulating:
BER using convolutional coding with QPSK and 16QAM modulations in an AWGN and Rayleigh channels as a function of the average SNR (i.e. average ES/N0). The (punctured) convolutional code is the one standardized in IEEE 802.16 with a polynomial generators of {133o, 171o}, constraint length L=7 and a native code rate r=1/2.
