Thank you so much for your site. I am a practising systems engineer, who has to integrte communication systems into larger systems of systems. Your site is invaluable to me for refreshing my understanding of communications concepts and designs, so that I can specify meaningful capabilities when I talk to true communications engineers.
Hi Charan
I think there maybe a typo. In equation 40, Tb = 2*Ts for QPSK (relationship between symbol and bit time). I think it should be Tb = Ts/2.
Rb = log2(M) * Rs
Rb = 2 * Rs
which would make Tb = Ts/2
My fear is that this incorrect relationship between symbol and bit time maybe used in the computation of BER based on Euclidean distance. Could you please look into this or correct me if I misunderstood
