07 Aug 2009	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
