Abstract
A sequential decoder for use in broadband mobile communications and a receiver including the sequential decoder. The sequential decoder computes likelihood values by referring to histories of paths to reduce the required computational effort. The paths include signal points having small tap coefficient values in an equalizer with a transversal filter, and may also include paths within a constraint length which are old in time.
