The channel knowledge at the transmitter side is usually obtained through feedback from the receiver. Assume that the channel coherence time of a wireless channel is 0.2 ms. Determine the feedback load of the following systems in bits/second: (i) selection-based transmit diversity system with L = 4; (ii) transmit diversity system based onAlamouti scheme with L = 2; and (iii) MRC-based transmit diversity with L = 2 antennas. Assume the real and imaginary parts of the channel gains are each quantized to 8 bits.
