Large System Analysis of Game-Theoretic Power Control in UWB Wireless Networks with Rake Receivers (0704.2017v1)
Published 16 Apr 2007 in cs.IT, cs.GT, and math.IT
Abstract: This paper studies the performance of partial-Rake (PRake) receivers in impulse-radio ultrawideband wireless networks when an energy-efficient power control scheme is adopted. Due to the large bandwidth of the system, the multipath channel is assumed to be frequency-selective. By using noncooperative game-theoretic models and large system analysis, explicit expressions are derived in terms of network parameters to measure the effects of self- and multiple-access interference at a receiving access point. Performance of the PRake is compared in terms of achieved utilities and loss to that of the all-Rake receiver.
