This paper investigates the information- theoretical capacity of the Max-SNR multi-user diversity system with quantized channel state information(CSI) under slow fading channels. General optimal quantization problems under the condition with or without transmit power control are derived. Numerical results show that the capacity with 4 bits optimal quantization is almost enough to approach that of...
This paper studies the optimal power control which can maximize the information-theoretical sum rate of the uplink of multi-cell, multi-user cellular systems equipped with successive interference cancelation (SIC). One important property for the optimal power control is presented: for the optimal power allocation, there will be at least one user transmitting at peak power in the system, and at most...
In this paper, we present two closed loop transmit diversity schemes for the systems which have designed closed loop power control scheme where the transmitter has equipped with two antennas and the receiver has one antenna. The proposed schemes do not require any additional feedback bits but utilize only the existing closed loop power control command bit in the system. The two proposed schemes are...
