针对高服务质量(Qos)模式和高优先级医疗应用，提出了三种不同的用于IEEE 802.15.6IR-UWB(脉冲无线超宽带)WBAN(无线体域网络)收发信机的DBPSK(差分二进制相移键控)解调技术。在不同的WBAN信道模型(CM3和CM4)下，评估了所提出的DBPSK解调技术的误比特率/误包率(BER/PER)性能。此外，还给出了采用所提出的解调技术的完整IR-UWB DBPSK WBAN收发机的误码率/误码率性能。误码率/误码率仿真结果表明，所提出的解调技术满足IEEE 802.15.6物理层定义的误码率/误码率要求。仿真结果表明，与基于相关检测的解调(CDD)和基于窗口检测的解调(WDD)相比，基于能量检测的解调(EDD)技术具有更好的误码率和误码率性能。从实现的角度来看，这反过来又降低了硬件复杂性。
In this paper, three different DBPSK (Differential binary phase-shift keying) demodulation techniques for IEEE 802.15.6 IR-UWB (Impulse Radio Ultra Wide-band) WBAN (Wireless Body Area Networks) transceivers are proposed for high QoS (Quality of Service) mode and for high priority medical applications. The proposed DBPSK demodulation techniques are evaluated under different WBAN channel models (CM3 and CM4) for Bit error rate /Packet error rate (BER /PER) performance. Further, the BER/PER performance of the complete IR-UWB DBPSK WBAN transceivers using the proposed demodulation techniques are also presented. The BER/PER simulation results show that the proposed demodulation techniques meet the specified BER/PER requirements of the IEEE 802.15.6 PHY (Physical) layer definitions. Simulation results clearly shows that the proposed EDD (Energy Detection based Demodulation) technique gives superior BER/PER performance in comparison to the other proposed CDD (Correlator Detection based Demodulation) and WDD (Windowing Detection based Demodulation) demodulation techniques. This, in turn, results in reduced hardware complexity from the point of view of implementation.
