  • For MIMO systems where channel state information is not acquired either at the receiver or at the transmitter, a novel family of full diversity unitary space-time block coding scheme is proposed in this paper, which combines Cayley transformation and the Diagonal Block Orthogonal Algebraic Space-Time (DBOAST) codes. The proposed space-time block codes can be applied to MIMO systems with even number of transmit antennas, which can achieve full transmit diversity and the rate of 1.5 symbol per channel use. The decoding of the proposed codes can be implemented by the sphere decoder at low computation complexity to achieve suboptimal results.
