摘　　要：In this letter,we propose a hybrid analog/digital detection algorithm,the Correlated In-terference Cancellation(CIC) algorithm,for Impulse Radio Ultra-WideBand(IR-UWB) system.The CIC algorithm correlates received signal with its delayed versions in the analog domain and samples the correlation output at the symbol rate.The symbol rate samples are processed in the digital domain to perform interference cancellation.Therefore,CIC works for high data rate systems with heavy In-terSymbol Interference(ISI).Simulation results show that CIC achieves good performance in typical UWB channels.In this letter, we propose a hybrid analog/digital detection algorithm, the Correlated Interference Cancellation （CIC） algorithm, for Impulse Radio Ultra-WideBand （IR-UWB） system. The CIC algorithm correlates received signal with its delayed versions in the analog domain and samples the correlation output at the symbol rate. The symbol rate samples are processed in the digital domain to perform interference cancellation. Therefore, CIC works for high data rate systems with heavy InterSymbol Interference （ISI）. Simulation results show that CIC achieves good performance in typical UWB channels.
