Abstract :
The symbol error rate (SER) analysis of a transmit beamforming system is investigated under delayed and limited feedback. Using the Lauricella hypergeometric series, the exact closed-form expressions of the transmit beamforming for SER with M-ary phase shift keying and quadrature amplitude modulation is derived under the delayed and limited feedback.
