Algebraic constructions of optimal space-time trellis codes

Hsiao-feng Lu, P. Vijay Kumar

Abstract

We first show the criteria for designing binary space-time trellis codes that achieve the optimal rate-diversity tradeoff. Based on the criteria, two systematic constructions of binary space-time trellis codes for any number of transmit antennas and any desirable rate are provided. Finally, by extending our work on the unified construction of space-time codes, these newly constructed binary space-time trellis codes are generalized to a series of codes over a much larger signal constellation, for instance, PAM, QAM and PSK modulations.
