Extracted text: Problem1) Determine the signal space representation of the four signals s (1), k = 1, 2, 3, 4, shown in Figure P3.2, by using as basis functions the orthonormal functions 1(t) and ,(t). Plot the signal space diagram, and show that this signal set is equivalent to that for a four-phase PSK signal. s(0) FIGURE P3.2 - VE
