Abstract
Based on the Complex Orthogonal Linear Dispersion (COLD) code, a novel linear Differential Space-Time Modulation (DSTM) design is proposed in this paper. Compared with the existing nonlinear DSTM schemes based on group codes, the proposed linear DSTM scheme is easier to design, enjoys full diversity and allows for a simplified differential receiver, which can detect the transmitted symbols separately. Furthermore, compared with the existing linear DSTM based on orthogonal design, our new construction can be applied to any number of transmit antennas. Similar to other algorithms, the proposed scheme also can be demodulated with or without channel estimates at the receiver, but the performance degrades approximately by 3dB when estimates are not available.
