Multi-Antenna Communications over Rapidly Fading Channels Estimation and Space-Time Coding
Abstract
This 3-year project dealt with development and testing of efficient algorithms for modeling and (blind) estimation of time-varying communication channels, and the resulting (self-recovering) antenna receivers and equalizers in rapidly fading mobile battlefield scenarios. Highlights of recent results include space-time coded transmit- and receive-diversity to combat noise, oscillator drifts, and Doppler effects; optimal wedding of beamforming with space-time coding; space-time-frequency coding for use over frequency-selective channels; space-time-Doppler coding for time-selective channels; and optimal training over doubly-selective channels.
