Abstract :
In this paper, downlink opportunistic scheduling is studied in a multiuser environment with single-antenna base station and users. Analytical symbol error rate (SER) expressions are derived under the assumptions of full and quantized channel state information (CSI) at the transmitter. These expressions are used to optimize the channel state feedback parameters.
