Design of robust redundant precoding filter banks with zero-forcing equalizers for unknown frequency-selective channels

Redundant multirate filter bank transceivers have been proposed for block-based transmission over channels whose characteristics are known at both the receiver and the transmitter. We propose a criterion for the design of such transceivers for applications in which the channel is not known at the transmitter. The design objective is the minimization of the average mean square error of the data estimates produced by a zero-forcing equalizer over …
