Power Controlled Channel Allocation for Multiuser Multiband Ultra-Wideband Systems
Published Monday, February 21, 2005The emerging ultra-wideband (UWB) system offers a great potential for the design of high-speed short-range communications. However, UWB faces a significant challenge in achieving a low transmit power level, while assuring adequate system performance. An efficient management of the limited power is thus a key to fully exploiting the advantages of...
