Energy-Efficient Quantization and Resource Allocation for TDMA with Finite Rate Feedback

We deal with energy efficient time-division multiple access (TDMA) over fading channels with finite-rate feedback for use in the power-limited regime. Through finite-rate feedback from the access point, users acquire quantized channel state information. The goal is to map channel quantization states...
