Abstract

Abstract:

A new family of space-time block codes is constructed, called diagonal block orthogonal algebraic space-time (DBOAST) block codes. It can transmit at a normalized rate of 1 symbol per channel use. It is proved that they can achieve the full transmit diversity with a larger coding gain than DAST block codes over quasi-static or fast fading channels. The capacity of an equivalent channel using the proposed code is analyzed. The performance merit of DBOAST block codes is confirmed by Monte Carlo simulations and compared with other space-time block codes.

Key words: wireless communication, MIMO systems, space-time codes, diversity, capacity
