摘要

在认知无线电(CR)系统中，频谱切换是影响传播路径性质的关键因素。因此，它可能会影响整个系统的覆盖率和性能。本文提出了一种新的频谱切换策略，以减少频谱切换的发生，从而获得更好的传输性能。具体来说，它提供了一种结合功率自适应方案的更好的信道选择策略。这是为了减少/避免干扰，也为了节省系统的电力消耗，从而得到一个更环保的通信系统。仿真结果表明，该方法在切换请求方面的性能提高了64%。此外，还对系统进行了误码率分析，并与其他系统进行了比较，以显示所保持的性能。

On Developing SeamlessSpectrum Handoff Strategyfor Cognitive Radio Networks

In Cognitive Radio (CR) systems, the spectrum handoff is a key-factor as it could affect propagation path nature. Accordingly, it may affect the overall system coverage and performance. In this article, a new spectrum-handoff strategy is proposed in order to minimize the occurrence of spectrum handoff and hence to achieve a better transmission performance. Specifically, it provide a better channel-selection strategy combined with a power adaptation scheme. This is to reduce/avoid interference and also to conserve power consumption in the system and hence get a greener communication system. The simulation results show an enhancement of up to 64%in switching requests. Also, the system is analyzed in terms of BER and compared to others to show the performance maintained.
