1. One signal constellation for QPSK is shown in the figure below. Assume the modulated signals experience an AWGN channel, and the signals are equally to be transmitted. The AWGN process n(t) is zero mean and Rn (T) = № 8 (7). Find the probability of signal transmission error for this QPSK modulation. No 5 S3 X -√√E 72 √ES TV -√ES x √E x S1 S4 r1 1.
