Closed-form designs of complex orthogonal space-time block codes of rates (k+1)/(2k) for 2k-1 or 2k transmit antennas

Abstract

In this correspondence, we present systematic and closed-form constructions of complex orthogonal space-time block codes from complex orthogonal designs of rates (k+1)/2k for 2k-1 or 2k transmit antennas for any positive integer k.
