Hello,I'm writing a project for a class but i'm having some difficulties in the theoretical part and i would like some help...In a transmition through AWGN with FSK modulation given that the bit error probability without encoding is
Pa= (1/2) *[e^(-Eb/(2*No))]
how can we prove that bit error probability using repetition code (n,1) is
Pb= (1/2) *[e^(-Eb/(2*n*No))] ???

 

Is your question the following?:

If Pa is the probability of one bit being wrong, what will be the probability of n consecutive bits being wrong?

Also, what are Eb and No?

In general, the probability of n events with probabilities Pa,Pb,Pn happening together is Pa*Pb*...Pn.
