Title: Space-Time Block Codes: A New Paradigm for Wireless Communications Using Multiple Transmit Antennas
Abstract: Space-time block coding is a new paradigm for communications over Rayleigh fading channels using multiple transmit antennas. These transmission schemes were invented jointly in the `Research Laboratories' and the `Strategic Technology Group' of the AT&T.
Encoding and decoding are extremely simple and these transmission schemes have remarkable properties. They also enjoy a very interesting and deep mathematical theory namely the `Theory of generalized orthogonal designs'.
These codes have been adapted for use at base stations and the handsets for the next generation wireless systems in Europe (UMTS). They are also currently being considered in the EDGE standardization committee.
We review examples of the scheme for both when the receiver knows or does not know the channel.
This is a joint work with A.R. Calderbank and H. Jafarkhani.
