Abstract
Recently, extensive effort has been taken to build fast-decodable (FD) space-time (ST) codes, especially called for due to the limited power resources available for mobile receivers. Although there have been numerous successful attempts that have resulted in reduced decoding complexity for a certain number of transmit antennas, a general method for constructing FD codes for a wider range of antenna combinations and rates is still missing. Here, this problem is solved by introducing a totally general framework for constructing full-diversity FD codes with non-vanishing determinants (NVD).
