Abstract :
We study joint feedback design for multiple access channel (MAC) over fading Gaussian Channel. The transmitters use partial channel-state information (CSI), which is obtained via an optimized feedback link. We develop a simple iterative algorithm for the design of CSI quantization to maximize the expected rate. Also, we show the performance by simulation result.
