Abstract: We show that for any (Q/spl times/M) space-time code S having a fixed, finite signal constellation, there is a tradeoff between the transmission rate R and the transmit diversity gain /spl ...

Two identical antennas are fed with a microstrip line of two branches with a phase shift to perform a Phase Shift Keying (PSK) modulation. Using Computer Simulation Technology/Microwave Studio (CSTMWS ...
