摘　　要：目前体域网(BAN)物理层相关算法的研究均基于自己设计的物理层方案。基于IEEE 802.15.6标准的物理层规范设计了BAN基带接收端的相关算法并进行了仿真分析。由于传输数据的突发性,首先基于前导序列设计了分组检测方案,获得数据的起始时刻与粗定时同步,然后进行频偏估计并进行频率补偿消除频偏的影响,最后利用扩展序列实现精确的符号定时同步。仿真结果表明:设计方案具有较好的解调性能。Current research on physical layer algorithm for body area network（ BAN） is mainly related to selfdesigned physical layer schemes. Based on physical layer specifications in IEEE 802. 15. 6 standard for BAN,related algorithms for baseband receiving end are designed and simulated. Because of the burstiness of BAN packets,packet detection scheme is first designed based on preamble sequence,to obtain initial time of data and coarse timing synchronization. Frequency offset estimation and frequency compensation are carried out to suppress influence of frequency offset. Accurate symbol timing synchronization is realized by using extension sequence.Simulation result show that designed scheme has good performance of demodulation.
