Transmitter optimization for noisy ISI channels in the presence of crosstalk

Transmitter optimization techniques for maximizing the throughput of linear ISI channels impaired by additive-Gaussian noise and crosstalk are presented. The transmitter ends of both single carrier and multicarrier transceiver structures are optimized subject to a fixed average input energy constraint. The effect of transmitter optimization on channel throughput is quantified by comparison with scenarios where both the desired user and the crosstalker use a flat energy distribution across the transmission bandwidth.
