Abstract

The embodiment of the invention discloses a data sending method for a multi-antenna system. The method is characterized by comprising that data information sent to a plurality of receiving ends is subjected to channel coding, interweaving and modulation processing, wherein the data information sent to each receiving end adopts different interwoven patterns to interweave respectively; and the data information processed through modulation and the interwoven pattern information adopted by the data information are sent to a plurality of the receiving ends. The embodiment of the invention also discloses a data receiving method for the multi-antenna system and a device thereof. The method can increase the signal-to-noise ratio of a signal received by the receiving end of the multi-antenna system and improve the performance of the system.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data sending and receiving method and device of a multi-antenna system. Background technique [0002] In order to enhance the performance of the mobile communication system, MIMO (Multiple Input Multiple Output, multiple input multiple output) technology. MIMO technology refers to the use of multiple transmitting antennas and receiving antennas at the sending end and receiving end respectively, and signals are transmitted and received through multiple antennas at the sending end and receiving end, thereby improving data transmission rate and / or bit error rate. The transmitting antenna used in the MIMO technology can be a physical antenna or a virtual antenna. In 3GPP TR 25.876V1.7.1, the virtual antenna (Virtual Antenna) technology is proposed. This technology provides multiple virtual antenna ports. After the multi-channel transmission signals are respectively sent to multi...
