A block floating point treatment to finite precision realization of the adaptive decision feedback equalizer

► Presents a block floating point (BFP) realization of adaptive decision feedback equalizer. ► Suitable BFP format chosen to represent feedforward and feedback coefficient vectors. ► Separate update relations for the coefficient mantissa vectors and exponent derived. ► Overflow controlled by certain dynamic scaling of data and new upper bound on step size. ► Deploys mostly fixed point operations, more efficient than a FP realization
