英文摘要： Tranditional wireless communication systems are difficult to meet the requirements of miniaturization,low power and high-data rate at health monitoring system for portable and remote telemetry applications. Ultra wideband(UWB) technology has the advantages of low-power, high-data rate and the immunity to multi-path fading and spectrum-compatible with other communication systems.This subject intends to study a UWB health monitoring and telemetry system for wearable wireless body area network(WBAN) application.A new UWB communication system for wearable WBAN application will be established by channel modeling and system design. Then the system will be integrated into a chip using CMOS technology. (1)Research of near-field propagation and attenuation characteristics of UWB WBAN signal on human body will be fulfilled. A UWB wireless communications channel model suitable for WBAN will be established. (2)Sensor signal processing,UWB WBAN communication system transceiver structure and integration circuit theory will be researched.It will meet the detect requirements of the weak physiological signals of human body as well as the requirements of wireless health monitoring and telemetry system for multiple access, low power, high data rate application. (3) The wearable health monitoring and telemetry systems will be i
