A New Approach for Optimal Power Control in the ..

The Electrical Engineering faculty study the following areas: optical and solid-state devices, including quantum electronics and optics, integrated electro-optics and acoustics, design of semiconductor devices and materials, analog and mixed-signal IC design, microwave and microwave devices, and scanning acoustic micro­scopy; systems engineering and signal processing, including communication theory, machine vision, signal processing, power electronics, neural networks, communications networks, systems engineering, and control systems. Related communication networks topics are also addressed by the Networked Systems M.S. and Ph.D. degrees (listed in the of the Catalogue).

Abstract—We determine the optimal adaptive rate and power control strategies to maximize the total throughput in a multirate code-division multiple-access system.

During my PhD studies, I acquired a rich experience in designing, building and experimenting with wireless systems and testbeds.

Distributed antenna diversity employs separately installed, but cooperating, antennas within a single base-station; it has been proved that the uplink capacity (per cell) in terms of maximum achievable SIR (signal-to-interference ratio) is linear with the number of deployed antenna units. While in the downlink, because of the multiple-to-one propagation topology, equal power (transmission power at each antenna) allocation (providing equal SIR) in the base-station results in fixed SIR at the mobile terminal, irrespective of the number of base-station antennas used. A transmission scheme, using optimal power allocation and SIR-balanced power control, is proposed to increase the SIR by exploiting multiple base-station antennas. The downlink diversity (called antenna-multipath diversity) transfers the antenna diversity to multipath diversity by utilizing the spread-spectrum signal property. If optimal, rather than equal, power allocation is employed with antenna-multipath diversity, the SDMA advantage can be exploited. The optimisation result shows that, for a particular user, transmitting a signal from one antenna, instead of all base-station antennas, gives better SIR performance. The SIR CDF has been examined by simulation to verify this scheme. Compared to sending from all antennas, the result shows, that for 8 users, this scheme yields improved SIR by 3 dB with 5 antennas. The SIR advantage increases with increasing numbers of antennas and decreases, however, with increasing numbers of users in the cell.
