摘要： Disclosed is a ghost cancellation system based on an enhanced ghost cancellation reference signal for noisy environments. The received analog television signal is first subjected to a digitization step for processing in the digital domain. A wavelet de-noising operation is applied on the reference signal to remove undesired noises before a communication channel is estimated, and filter coefficients are optimally determined. The digitized composite signals are then ghost-reduced by IIR and FIR filters. The power consumption and training time of the realized chip are decreased, which is ideal for mobile and platform applications.
