Abstract

The invention provides a low-complexity space-time keying discrete matrix generation method. Firstly, the value interval of each element of the discrete matrix is ​​discretized, so that the continuous optimization problem is transformed into a discrete optimization problem, and the search interval is correspondingly transformed from infinite data sets to finite data sets. Then an alternate optimal method is proposed to search for the optimal discrete matrix set. This method only optimizes one data in the discrete matrix set each time, and then optimizes the next data on this basis until all the data are optimized. Compared with the method of finding the optimal matrix through a large number of random searches in the traditional space-time keying, the present invention can greatly reduce the complexity of the matrix search process and maintain excellent performance.
