Analog precoder and equalizer design for multichannel communication

This work addresses joint analog precoder and equalizer design for multichannel data transmission over the frequency-selective additive Gaussian noise (AGN) channel. The design goal is to maximize mutual information rate subject to a transmit power constraint. We assume a continuous channel model with precoder transmissions for M subchannels that lie in an n dimensional linear subspace of L/sup 2/(R). We first design the subspace according to the channel characteristics, and then design the precoders as functions in this subspace.
