Abstract
A method of generating good performing USTM constellations using the Cayley transform is proposed. The codes, which can be used for any number of transmit and receive antennas without channel knowledge, are designed based on an information-theoretic criterion, and lend themselves to polynomial-time near-maximum-likelihood decoding using the sphere decoding algorithm.
