Spatiotemporal Signal Processing in Wireless Communications

Abstract

Spacetime diversity can significantly enhance the performance of wireless communication systems. In this chapter we highlight the potential benefits, requirements and limitations of such systems. In the first half we provide a general treatment of the spacetime signal processing scenario and spacetime diversity and coding frameworks based on block spacetime codes. In the second half, a semiblind signal processing approach is presented and integrated with spacetime diversity and coding to form a realistic scenario for detection and estimation. Our aim is to illustrate the basic priciples and to suggest a realistic approach for implementation of spacetime wireless transcievers.
