Need some help in bit error rate calculation for QPSK when using Gray coding
Why is Probability of Bit Error = 2 times the Probability of Symbol Error in QPSK with Gray Coding. Is it because one bit error has the potential to cause two symbol errors (2 symbols where they ...

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 ...

CAN: End-Of-Frame for detecting stuffing errors?
The end-of-frame consists of 7 recessive bits. It is often written that it is used to detect stuffing errors by a receiver. I also read that if the 7th bit is driven to dominant level, the transmitter ...

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((...
