Receiver and receiving method

摘要

Embodiments of the present invention provide a receiver and a receiving method. The receiver comprises: a branch forming unit a plurality of signal branches; each of the signal branches comprising a joint processing unit; and the joint processing unit being used to eliminate an inter-carrier interference of the subcarrier signal in a present signal branch and the subcarrier signals in other signal branches adjacent to the present signal branch. With the embodiments of the present invention, the inter-carrier interference may be eliminated and the performance of the system may be improved; and the sampling rate of the analog digital converter may also be lowered.

主权项

1. A receiver, comprising:
a coupler, configured to divide a signal from a transmitter into multiple branches of subcarrier signals; and a plurality of signal branches, each of the signal branches comprising a joint processing unit, the joint processing unit being used to eliminate an inter-carrier interference of the subcarrier signal in a present signal branch and the subcarrier signals in other signal branches adjacent to the present signal branch; wherein the joint processing unit comprises:
a plurality of filters, each of the filters being used to filter the subcarrier signal in the present signal branch and the subcarrier signals in other signal branches adjacent to the present signal branch according to a filtering coefficient; andan adder, configured to add up the output results of the plurality of filters.
