INTERFERENCE SUPPRESSION METHOD AND DEVICE

摘要

An interference suppression method and device. The method comprises: determining whether each OFDM symbol in a current time slot is subjected to interference on a sub-carrier set corresponding to each PRB; determining, for each OFDM symbol under interference, an interference matrix on a sub-carrier set corresponding to each PRB where the interference is located; and performing interference suppression on data symbols on the sub-carrier set corresponding to each PRB under interference according to the interference matrix on the sub-carrier set corresponding to each PRB under interference. The sub-carrier set corresponding to each PRB under interference is a sub-carrier set corresponding to the PRB where the interference on each OFDM symbol under interference is located, and the interference matrix on the sub-carrier set corresponding to each PRB under interference is an interference matrix of each OFDM symbol under interference on the sub-carrier set. Because the interference characteristics of the data symbols are taken into consideration, interference on the data symbols can be effectively suppressed.
