New space-time block codes for high throughput efficiency
Most current space-time block codes are designed based on an orthogonality principle. By relaxing the orthogonality requirement, it is possible to construct new codes with higher throughput efficiency. In this paper, new non-orthogonal space-time block codes for three transmit antennas are proposed, achieving throughput rates larger than those of currently known orthogonal designs. The proposed codes are found through a code search based on the rank criterion, determinant criterion and rank distribution. Performance results through Monte Carlo simulations demonstrate that there is a trade-off between the error-rate, diversity order and throughput rate.
