摘要: abstract:In this paper, we propose a direct-sequence ultra-wideband (DS UWB) transmission system for wireless telemedicine system. An essential feature of this system is that it offers larger power and schemes providing significant error protection for the transmission of medical information that requires higher quality of service (QoS). To realize maximum resource utilization, or minimum total transmission power, we also include an M-ary binary offset keying (MBOK) strategy into the system. Thus, in the proposed medical system, high power, a long length MBOK code, and scheme providing significant error protection schemes are employed for the transmission of medical messages that require a stringent bit-error rate (BER). In contrast, low power, short length MBOK codes, and less capable error protection schemes are provided for messages that can tolerate a high BER. A simulation is carried out to verify the proper functioning of the proposed system in a practical wireless telemedicine scenario.
