On the Construction of DMT-Optimal AST Codes with Transmit Antenna Selection

Camilla Hollanti, Hsiao-feng (Francis) Lu, On the Construction of DMT-Optimal AST Codes with Transmit Antenna Selection. In: Proceedings of 2008 IEEE International Symposium on Information Theory (ISIT), 2008.

Abstract:

In this paper, two possible techniques
are considered as a solution to the asymmetric coding problem. By the asymmetric coding problem we mean that the number of receive antennas is strictly less than the number of transmit antennas, and the task is to do design a system enabling efficient decoding using e.g. a sphere decoder. Specifically, given any desired
antenna selection pattern, the proposed method will yield codes
using exactly the specified pattern, and moreover, the resulting
codes are proved to achieve the diversity-multiplexing tradeoff associated with such selection
pattern. Thus, our scheme can easily be implemented in both
situations described and is guaranteed to achieve the optimal performance.
