An information source has an alphabet {o, a, r, t, h, g, n, l} with corresponding probabilities {0.3

An information source has an alphabet {o, a, r, t, h, g, n, l} with corresponding probabilities {0.3, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1, 0.1}.

d) Design a QPSK modulation system for this. Evaluate the SER, sketch the constellation diagram, gray code the symbols. You can assume a constellation radius of A.

e) What would the waveform look like if the word 'orthogonal' is transmitted?
