please ans this q
= Problem 2. A Binary signal amplitude set Ak, k = 1, 2 is given by A1 = 12, A2 = 4. The corresponding signalling waveforms are given by = T T Sk(t) = 了。 2 Ak cos(wct), 11 < < 1/1 2 After flat fading, the received inphase signal is given by (check One note), 3 I(t) = XAX Cy cos((wc + wn)t + Pn) + 1,() n=1 Similarly, you can formulate for the quadrature received signal. Derive the optimum condition for non-coherent detection of the binary symbols. Also draw the optimum detector block diagram.
