چکیده

Antenna array beamforming and power control have been studied separately to increase the capacity in wireless communication networks. Recently, the two were considered jointly in a system with power control capabilities which uses antenna array at the receiver only or the transmitter only. In this paper we formulate and study the joint beamforming and power control problem in a system with antenna arrays both at the transmitter and the receiver. Two algorithms are proposed for the joint problem. The capacity of the system that has beamforming capabilities at both sides is compared with the system that has one side beamforming capabilities only. The increase in the network capacity is evaluated through a numerical study.

Joint transmitter receiver diversity for efficient space division multiaccess

Beamforming problem is studied in wireless networks where both transmitters and receivers have linear adaptive antenna arrays. Algorithms are proposed that find antenna array weight vectors at both transmitters and receivers as well as the transmitter powers with one of the following two objectives: 1) to maximize the minimum signal-to-interference-and-noise ratio (SINR) over all receivers and ...

Joint Closed-Loop Power Control and Base Station Assignment for DS-CDMA Receiver in Multipath Fading Channel with Adaptive Beamforming Method

In this paper, we propose smart step closed-loop power control (SSPC) algorithm and base station assignment based on minimizing the transmitter power (BSAMTP) technique in a direct sequence-code division multiple access (DS-CDMA) receiver in the presence of frequency-selective Rayleigh fading. This receiver consists of three stages. In the first stage, with conjugate gradient (CG) adaptive ...

Channel capacity and beamforming for multiple transmit and receive antennas with covariance feedback

Abstract—We consider the capacity of a narrowband point to point communication system employing multiple-element antenna arrays at both the transmitter and the receiver with covariance feedback. Under covariance feedback the receiver is assumed to have perfect Channel State Information (CSI) while at the transmitter the channel matrix is modeled as consisting of zero mean complex jointly Gaussi...

Interference management for CDMA systems through power control, multiuser detection, and beamforming

Among the ambitious challenges to be met by the third-generation systems is to provide high-capacity flexible services. Code-division multiple access (CDMA) emerges as a promising candidate to meet these challenges. It is well known that CDMA systems are interference-limited, and interference management is needed to maximally utilize the potential gains of this access scheme. Several methods of...
