Abstract

The invention provides a wireless communication receiver, an interference elimination method and device thereof and a signal demodulation method. The wireless communication receiver at least comprises two receiving antennas. The interference elimination method comprises the following steps: carrying out channel estimation on an interference cell based on received signals; calculating correlation of interference cell emission signals on each receiving antenna through the channel estimation result of the interference cell; and carrying out interference elimination operation on signals received by the receiving antennas according to the correlation of interference cell emission signals on each receiving antenna. According to the technical scheme, the interference elimination is performed on the received signals through the wireless communication receiver under the condition of not increasing too much operation; the wireless communication receiver is allowed to have a certain interference inhibition capability; and thus the reception performance is improved under the condition of same frequency interference.

Description

technical field [0001] The invention relates to the communication field, in particular to a wireless communication receiver, an interference elimination method and device thereof, and a signal demodulation method. Background technique [0002] Due to the limitation of spectrum resources, many communication systems are now networked at the same frequency, such as the Long Term Evolution (LTE, Long Term Evolution) system, or some communication systems, such as the Global System for Mobile Communications (GSM, Globe System of Mobile Communication) , Wideband Code Division Multiple Access (WCDMA, Wideband Code Division Multiple Access) systems using high-speed packet access technology (HSPA, High-Speed ​​Packet Access), etc., due to network optimization or networking design, there will also be interference from other cells. [0003] Multiple-Input Multiple-Output (MIMO, Multiple-Input Multiple-Output) technology refers to the use of multiple transmitting antennas and receiving ...
