Abstract

In the technical solution of an interference alignment iterative calculation method, device, storage medium, and computer equipment provided by an embodiment of the present invention, according to the acquired initial interference subspace matrix, the acquired local channel gain matrix, and the transmit precoding matrix, by pre- The established optimization algorithm model generates an updated interference subspace matrix, and inputs the updated interference subspace matrix to the base station so that the base station generates an updated transmit precoding matrix; adds 1 to the set iteration number n; According to the updated interference subspace matrix output by the received transceiver, through the pre-established optimization problem model, output the updated transmit precoding matrix, and add 1 to the set iteration number, if the iteration number is equal to The number of times is preset, and the output interference subspace matrix and transmit precoding matrix are taken as the optimal solution, which improves the anti-interference performance of the transceiver, thereby improving the robustness of the iterative calculation of interference alignment.

Description

【Technical field】 [0001] The present invention relates to the field of communication technologies, and in particular to a method, apparatus, storage medium and computer equipment for iterative calculation of interference alignment. 【Background technique】 [0002] In the related art, the currently designed robust interference alignment transceiver algorithm uses Kalman channel prediction to improve the channel capacity; the robust interference alignment algorithm that minimizes the mean square error reduces the algorithm complexity, and analyzes the algorithm bit error rate at the same time; Analyzing and derivation, the transmitter only knows the upper and lower bounds of the average mutual information capacity of the system under the noise-contaminated channel state information, and then the interference alignment scheme is obtained. The interference signal is reconstructed; finally, the original problem of channel error is transformed into a semi-definite programming probl...
