Hi, i have a problem with calculating the bit error probability of BPSK modulation using the matched filter:
As it's known well the bit error probability of BPSK (with matched filter at the receiver) can be written as:
P(e) = ½*erfc(√SNR)
My problem is that from an article i've read that if the matched filter output is reduced by a factor for example A the bit error probability changes into this form:
P(e) = ½*erfc[(√SNR)*A]
What's the reason for that and what's the relationship between matched filter output and bit error probability for BPSK? Thanks in advance...
