A critical component in detection under intersymbol interference (ISI)

and in turbo equalization is the BCJR algorithm. We study two approaches

to reducing its computation. First, the state space is reduced by

optimizing the receiver's phase-maximizing all pass filter. Then the state

space used by the BCJR calculation is reduced by breaking the state

into an offset and a main state. These procedures are

demonstrated by ISI detection and turbo equalization over strongly

bandlimited channels.
