Abstract :
Reduced-state sequence estimation (RSSE) with tap-selectable decision-feedback is presented which significantly reduces the computational complexity of RSSE for sparse postcursor impulse response channels. Prefiltering is considered for more general channels, where a few channel coefficients constitute a large portion of the overall channel energy. Tap-selectable RSSE is less computationally expensive and better suited for high-speed VLSI implementation than prior reduced complexity RSSE techniques
