摘要
认知无线电中,干扰温度模型用来在提高频谱使用率的同时保证主用户接收机处干扰在允许范围之内。对干扰温度模型进行了研究,对使用干扰温度模型的认知无线电网络(包括无线WAN和无线LAN)所能实现的容量进行了分析。仿真结果表明理想模型和一般模型所能实现的容量都较低,从而说明干扰温度模型比较适合于数据速率要求较低的应用。
Interference temperature model can be used in cognitive radio to improve the spectrum utilization and guarantee that the interference at the primary receivers is tolerable. The interference temperature model was analyzed in detail. The achievable capacity under cognitive radio networks including wireless WAN and wireless LAN was also analyzed. Simulation results show that the achievable capacity is low and hence the interference temperature model is appropriate for applications requiring low data rate.
