Abstract

Cognitive radio (CR) improves radio spectrum utilization and offers new opportunities for future wireless services. It is designed to operate in frequency bands that are licensed to other primary radio users while ensuring no harmful interference to the licensed users' operations. By knowing the geo-locations of the CRs and the licensed users, it is possible to allow CR to access licensed bands without causing interference. In this paper, a transmission power control scheme for CRs is proposed to minimise the interference to licensed users. The scheme utilises mainly location information to estimate primary systems service reliability as the main power control indicator to determine the transmission power. Primary system interference analysis has been conducted as a part of the scheme and a model of an exclusion zone centred on a primary transmitter (PT) has been developed. This model is also specified by the Federal Communications Commission (FCC). Interference analysis at the centre and the edge of the exclusion zone has been performed by other researchers. In this paper, an analysis of the interference power level across the entire coverage area has been conducted. The effect of shadowing has also been included in the evaluation. The interference power statistics have been analysed for the entire coverage area. Analytic studies and Monte Carlo simulations are in agreement.
认知无线电发射功率控制初级系统干扰分析
认知无线电(CR)提高了无线电频谱利用率,为未来的无线业务提供了新的机会。它的设计目的是在发牌给其他主要无线电用户的频带内工作,同时确保对持牌用户的操作没有有害干扰。通过了解CR和许可用户的地理位置,可以允许CR访问许可频段而不会造成干扰。本文提出了一种传输功率控制方案,以减少对许可用户的干扰。该方案主要利用位置信息估计主系统业务可靠性,作为确定传输功率的主要功率控制指标。作为方案的一部分,进行了一次系统干扰分析,并建立了以一次发射机(PT)为中心的隔离区模型。该型号也是美国联邦通信委员会(FCC)指定的型号。其他研究人员已经对隔离区中心和边缘的干扰进行了分析。本文对整个覆盖区域的干扰功率水平进行了分析。阴影的影响也包括在评估中。对整个覆盖区域的干扰功率进行了统计分析。分析研究和蒙特卡罗模拟结果一致。
