- W2137258664 abstract "An ultra-wideband channel is expected to exhibit different delay characteristics in different bands. In this paper, wideband channel delay characteristics are studied and delay parameters are found considerably different over frequency bands 3.1-4.6GHz. Based on this observation, an adaptive timing synchronization scheme (ATS) which estimates and maintains the timing delays of each band separately is proposed. The performance of ultra-wideband (UWB) Multi-band OFDM (MB- OFDM) system with ATS algorithm is studied through computer simulations. It is shown that ATS gives signal-to-noise ratio (SNR) improvement of 1.7 dB at Bit Error Rate (BER) of 2×10 -2 , 2.2 dB at BER of 7×10 -3 , and 1.1 dB at BER of 5×10 -3 for CM4, CM3, and CM2 respectively for uncoded MB-OFDM system over a non-adaptive synchronization scheme (5)." @default.
