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

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

For some reason, when loading, sim_qpskgray[1] comes up. Don't know why but you need to resave without the brackets and 1 [1] with sim_qpskgray.m
When I get some time, I will add some multipath to the program and see if it gives acceptable results.

Try looking at Gremont,B under author index for Viterbi decoding. Make sure you load MPSK first with Q function. Happy fathers day.

12 Jun 2008 UWB Receiver/Transmitter Using Continuous Wave M-file uses random data which modulates a carrier to configure a BPSK UWB transmitter/receiver syste Author: J C C, J

I would suggest you enter JC under author and look at QPSK TX and IQ Corralation RX. I used a simple RC low pass impulse response with the filter function since I don't have the butter function. You might also try replacing the multipliers with the xor function. You get the same results. It also uses a one bit flash converter (my definition and opinion)-happy fathers day
