12 Oct 2009	QAM Tutorial2 This m-file calculates the theoretical exact(in AWGN) SER verses Eb/No for even number of bits per s Author: J C	izzat, muhammad	i got error ~??? Index exceeds matrix dimensions. Error in ==> QAM16_TUTORIAL at 14 qam = constellation_qam1(floor((64)*randint(1,10000))+1);%Generate 16QAM symbol sequence(complex)
07 Aug 2009	QPSK Simulation/Gray Coding/Rayleigh Fading This m-file shows a baseband simulated version of QPSK with Gray coding (Rayleigh fading and AWGN ad Author: J C	Mak	Hi, krishna .. i have been working on viterbisim.m which is a built-in matlab example for understanding the ber tool.. i that i have tried to change the code rate to 2/3 with trellis structure of t = poly2trellis([5 4],[23 35 0; 0 5 13]); but output ber graph is completely unexpected n highly fluctuated.. i m not working on simulink ..plz help me how can i resolve this issue .. basically my project is on mimo-ofdm so far i have done ofdm transceiver which works ok without rayleigh which is like this data source ->FEC(2/3)->qpsk->ofdm ......but i need to send bits in a loop for more accurate ber that is i dont have to guess in advance ! thats y i m working on viterbisim.m... plz help m i have hardly got 2months to submit it ... thanks in advance

14 Feb 2009	MPSK Simulation (BPSK,QPSK,8PSK) This m-file simulates MPSK (theoretical and simulated) with Gray coding Author: J C	Holly	Can anyone help me? I face the problem to complite the matlab code with the following error: ---------------------------------------------------------------------- ??? Undefined command/function 'graymapPSK'. Error in ==> MPSK at 49 symbols = graymapPSK(bits); % gray code map to symbols -----------------------------------------------------------------------
