Performance bounds and cutoff rates for data channels affected by correlated randomly time-variant multipath fading

The symmetric cutoff rate is derived for quadrature-amplitude-modulated (QAM) block-coded data transmissions over noisy links affected by time-correlated multipath-phenomena which introduce intersymbol interference (ISI) in the received signal. Maximum likelihood (ML) decoding supported by perfect channel-state information (CSI) is assumed. Due to the presence of time-correlated ISI phenomena, the resulting transmission link constitutes an example of a continuous-state channel with memory.
