### Given the following signalling elements design the optimum receiver?

Given the following signaling elements, \begin{align} g_1(t) &= A \quad \text{for} \quad -T/4 < t \leq 0 \\ g_2(t) &= A \quad \text{for} \quad 0 < t \leq T/4 \\ g_3(t) &= A \quad \...

### Degradation of BPSK system using matched filter with a timing error

Given a BPSK system with: \begin{align*} s_1(t) &= Au_T(t) \\ s_2(t) &= -Au_T(t) \\ \end{align*} where $u_T(t)=1$ for $0<t<T$, and zero otherwise. Given $A > 0$, and Gaussian white ...

### Determining signal using Optimal receiver(Matched filter)

I'm given a signal that has been passed through a noisy channel using binary polar signaling with a pulse value of p(t) = 1. The receiver is coherent and the length of each pulse (in samples) is 10 ...
