Missouri University of Science and Technology ITC/USA 2008 Conference Proceedings / The Forty-Fourth Annual International Telemetering Conference and Technical Exhibition / October 27-30, 2008 / Town and Country Resort & Convention Center, San Diego, California Unitary space-time codes are a coding technique for unknown (i.e. non-coherent) multiple-input multiple-output (MIMO) channels. The unitary constellation symbol-error rate performance is determined by the diversity product and diversity sum metrics of the constellation. Numerous techniques have been presented over the last few years for constructing unitary space-time codes with continually improving diversity products and sums. Other work has focused on determining bounds on the optimal diversity product and sum for a given number of transmit antennas and constellation size. This paper presents a comprehensive survey of known construction techniques and bounds for unitary space-time codes, and also reports a variety of new constellations that have been constructed with improved diversity product or sum. These new constellations are documented along with a list of the currently best known codes and bounds. In many cases, a large gap between the bound and best known constellation exist. This result suggests areas of focus for improved constructions or tighter bounds. 2008-10 text Proceedings 0884-5123 0074-9079 http://hdl.handle.net/10150/606192 http://arizona.openrepository.com/arizona/handle/10150/606192 International Telemetering Conference Proceedings en_US http://www.telemetry.org/ Copyright © held by the author; distribution rights International Foundation for Telemetering International Foundation for Telemetering |
