摘要 无线体域网(WBAN)在医疗保健方面有着巨大的潜在应用价值,但分配给生物医疗的超宽带(UWB)无线频段和IEEE802.11a WLAN的频段部分相重叠,因此UWB WBAN设备将会受到IEEE802.11a WLAN信号的干扰。基于已有的跳时扩频脉冲位置调制(TH-PPM)和直接序列扩频脉冲幅度调制(DS-PAM)超宽带系统模型,构建UWB WBAN物理层干扰模型。通过误比特率仿真,对比分析了DS-PAM UWB WBAN系统与TH-PPM UWB WBAN系统在IEEE802.11a WLAN信号干扰环境下的可靠性。结果表明,DS-PAM UWB WBAN系统较THPPM UWB WBAN系统具有更好的抗干扰性能。 WBAN (Wireless body area network) has great potential application value in the field of health care. However, the uhra-wideband radio frequency assigned to biological care overlaps with the IEEE802.11a WLAN frequency band. For this reason, the UWB WBAN equipment would be interfered by the IEEES02.1 la WLAN signal. Based on existing time hopping pulse position modulation (TH-PPM) and direct sequence pulse amplitude'modulation (DS-PAM) UWB system model, the UWB WBAN physical layer interference model is constructed. Via the system reliability analysis and simulation, the bit error rate of DS- PAM UWB WBAN system and the TH-PPM UWB WBAN system are compared under the IEEES02.1 la WLAN signal interference environment. The experiment results indicate that the DS-PAM UWB WBAN system has better anti-interference performance than the TH-PPM UWB WBAN system.
