Exercise on PPM modulation bit rate
A digital communication system uses N=15 identical routes. The modulation used is 2-PPM. Calculate the value of $$ \varepsilon_b/N_0 $$ on the exit from the first route so that a final error ...

Error probability of BPSK with intersymbol interference
Consider an AWGN channel with BPSK modulation. Assume that
the information bits are i.i.d. Bernoulli with parameter 0<p<1,
we have ISI due to a timing offset at the transmitter, and
the decoder ...

Does Carrier frequency offset (CFO) means difference of the message frequency and integrator?
Can anyone here tell me what is CFO? Initially, I thought it might be when the message signal mi, that is
$$r(t) = 2P cos(2\pi fc*fi+\delta f)$$ doesn't match with integrator $$\int_0^T r(t) * cos((...
