@Aditya: Your equation for symbol error rate is correct.

Hi…
Thank you for this article…

I want to ask something about relation between SER and BER. To compute BER, i can use the formula :

BER = number of bit error / total bit

how about to compute SER? Is it similar formula like BER in simple way?
like :
SER = number of symbols error / total symbols

or another to compute SER ?

Thank you…

@farrakh: Sorry, I have not discussed Nakagami fading in any posts till date.

slam krishna
do u have bit error or symbol error simulations in nakagami_m channel.or related simulations with nakagami_m channel.
if u have plz email me.and plz email me ebook of bit error probability in awgn channel

thanks

@ananta: You may find the M-QAM symbol error rate in AWGN simulation model @

@ananta: If the channel is AWGN, the symbol error rate equation holds good for OFDM too. I have not posted code for M-QAM in OFDM case.

Could you help me find matlab script for M-QAM that is used on OFDM?

Thank You
