摘　　要：无线体域网(WBAN)作为最近的研究热点,具有移动灵活,部署方便等特点。由于不同频率点的信道参数存在相当的差异,同时无线信道变化较快,网络节点能量受限。因此在WBAN中,通过频谱感知,选择合适的空闲信道进行数据传输则显得至关重要,现总结比较了三种常见的频谱检测方式,并阐述了以低功耗为目的的系统硬件实现和算法实现。WBAN has become the hot spot of recent researches due to its prominent characters of highly portable and easily deployable.Since the parameters of wireless channel are significantly different under various channel frequency,together with the rapid change of channel characters and strict limitation on nodes＇ energy consumption,choosing some idle channels with the help of spectrum detector is quite important and necessary.This paper compares three common methods on the aspect of spectrum detection and describes the low-consumption oriented approach of realization of hardware system and algorithm implementation.

关 键 词：无线体域网 频谱检测 能量受限
