Embodiment Construction
[0054] refer to figure 1 , the system on which the present invention depends includes: 4 transmitting antennas, 8 or 6 receiving antennas, and the modulation mode is 4QAM. At the transmitter, the serial transmission sequence is converted into a parallel transmission sequence after space-time coding, and then the parallel sequence is modulated and sent out. At the receiving end, the received signal matrix is R': R'=HX+B, where R' is the received signal matrix, H is a channel matrix that obeys the complex Gaussian distribution with independent elements, X is the transmitted information sequence, and B is Gaussian White noise matrix.
[0055] The present invention blindly recognizes the space-time code pattern used by the sending end according to the received signal matrix R'.
[0056] refer to figure 2 , the concrete realization of the present invention is as follows:
[0057] Step 1, get the received signal matrix R':
[0058] The receiving end receives the signal seque...
