Question:

For M-ary PSK, the transmitted signal is of the form

s_i (t) = A cos(2πt + iπ / 2), i = 0, 1, 2, 3, for 0 ≤ t ≤ 1

s_i (t) = A cos[4πt + (i - 4)π / 2], i = 4, 5, 6, 7, for 0 ≤ t ≤ 1

(a) Find a set of basis functions for this signaling scheme. What is the dimension of the signal space? Express s_i(t) in terms of these basis functions and the signal energy, E = A² / 2.

(b) Sketch a block diagram of the optimum (minimum P_E) receiver.
