Embodiment Construction
[0022] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0023] see figure 1 , both conventional M-PSK / QAM and activated scattering matrices can be used to transmit information bits. The invention utilizes unit matrix to move circularly in the matrix to construct the scattering matrix. First of all, the scattering matrix of the GSTSK-CI scheme can be designed simply and systematically, and at the same time, it does not require angle optimization and computer optimal search; secondly, the GSTSK-CI scheme is suitable for any situation where the number of transmitting antennas is greater than 2, and it is better than the existing solution, the present invention can achieve higher spectral efficiency, especially in each transmission interval, when P is activated from Q scattering matrices, when Q P When the value of is larger,...
