The multiple-input multiple-output (MIMO) channel model, which is introduced by applying multiple antennas at the transmitter and the receiver, has significantly improved the capacity of wireless channels. Modulation techniques are used in MIMO models to map the source sequence into multiple sequences that are to be transmitted in different antennas. Equalization is a technique used by the receiver to compensate for channel distortions. Modulation and equalization techniques that incorporate long-response and time-varying channels are a challenging issue for future wireless communication systems.This project aims to improve the existing modulation and equalization schemes, such that they allow for a higher transmission rate and faster moving speed of the mobile hosts. The researchers expect to develop a new efficient transceiver framework for future wireless systems. The major tasks include:investigating the influence of long-response and time-varying channels on the system performance in terms of multipath diversity, coding gain, and symbol (or block) error rate; anddeveloping a new transceiver model for long-response, time-varying channels. New modulation schemes and a channel-shortening equalizer will be the focus.
