GROUPED DECODING METHOD AND RECEIVER BASED ON PARTIAL INTERFERENCE CANCELLATION

摘要

Disclosed are a grouped decoding method based on the partial interference cancellation and a receiver for implementing the method. The method comprises performing triangular decomposition for the channel correlation matrix and performing inversion for the decomposed matrix; extracting a submatrix associated with a group of signals from the inversed matrix for each group of the transmitting signals which are divided into groups; obtaining the received signal vector corresponding to the group and the equivalent channel matrix corresponding to the group after eliminating the inter-group interference according to the orthogonal decomposed submatrix; and utilizing multiple-input and multiple-output detecting manner to detect the transmitting vector of the group of signals according to the received signal vector corresponding to the group and the equivalent channel matrix corresponding to the group. This technical scheme decreases the complexity of implementing grouped decoding and saves the processing resources of the receiver.
