However, in my design, there are two integrators. Reply Krishna Sankar March 28, 2010 at 1:51 pm @amit: In AWGN there is no difference between using BER for BPSK and BER for BPSK using OFDM. these would be very much helpful for my thesis. This feature is not available right now. navigate here

The given simulation code is very generic, and it plots both simulated and theoretical symbol error rates for all M-PSK modulation techniques (upto \(M=32\)).

Finally the simulated and theoretical symbol error rates are computed.

This filter is often a square-root raised cosine filter, but you can also use a Butterworth, Bessel, Chebyshev type 1 or 2, elliptic, or more general FIR or IIR filter. check over here Reply waheed December 17, 2009 at 6:23 pm Hello friends: i am working on MAP , ML decoding for convolutional codes..is there any one who too work on similar Thanks Reply Krishna Sankar November 8, 2009 at 8:39 am @Egerue: Do not change the division factor. I need the correct coe for my final project on my Bachelor degree. Fsk Bit Error Rate
Modulate the message signal using baseband modulation. M must have the form 2k for some positive integer k.berfading uses expressions that assume Gray coding. I will appreciate if you reply me soon. his comment is here Using gamma-gamma channel model.
G., Digital Communications, 4th ed., McGraw-Hill, 2001.  Simon, M. Biterr Matlab The error rate decreases after decoding because the Hamming decoder corrects some of the errors. Thanks.
For the case of 'fsk', rho must be specified before K.ber = berfading(EbNo,'psk',2,1,K,phaserr) returns the BER of BPSK over an uncoded Rician fading channel with imperfect phase synchronization.
