Power and waveform optimization for implant ultra-wideband communications enhanced by dynamic sparse control
Osaka Metropolitan University
It is important to determine efficient transmit power for ultra-wideband (UWB) communications, especially in implantable medical devices, to overcome large signal attenuation from a human body and to ensure reliable high-speed transmission.
Therefore, Osaka Metropolitan University researchers investigated the optimization of transmit pulse waveform to improve the communication characteristics under two regulations: extremely low power (ELP) regulation and specific absorption rate (SAR). Furthermore, a sparse control method was introduced to further optimize the balance between the performance and system complexity for medical implant applications. The proposed system achieved an average throughput of 40.3 Mbps as compared with the average throughput of 5.7 Mbps of the conventional UWB communication system.
