Abstract :
The whitened matched filter (WMF) is the optimum receiver filter for pulse amplitude modulation (PAM) and quadrature amplitude modulation (QAM) transmissions in the presence of intersymbol interference (ISI) and additive white Gaussian noise (AWGN). A new realization of the WMF is proposed, which incorporates very easy timing recovery for high-speed transmissions such as optical fiber communications. The proposed realization scheme uses a specially designed filter to equalize the ISI, such that only relatively simple timing recovery circuitry for ISI free signals will be needed
