Abstract

The invention relates to a method for using multi-antenna to receive and decode signal, and relative device. Wherein, it is characterized in that: iteratively decoding the receiving signal with disturb signal received by antenna; summing and averaging the likelihood ratio of treated information bit, to obtain the likelihood ratio of information bit; and in the iterative decoding process, it also combines the external information to obtain the prior information needed in next iterative decoding process. Therefore, the invention can fully use multi-sender antenna to improve the frequency spectrum utilization, to confirm the decoding property of MIMO system.

Description

technical field

[0001] The present invention relates to the technical field of wireless communication, in particular to a decoding method and device for realizing the separation of multi-antenna interference signals. Background technique

[0002] The high-speed development of Internet and mobile communication shows that there is potentially huge demand for high-speed wireless data services. Multi-transmission and multiple-reception antenna array (MIMO) can effectively improve the spectrum utilization of the channel. However, in order to achieve high-speed data transmission (BLAST) in the MIMO structure, the reliability of the system must be reduced due to signal interference, and at the same time, the reliability of data transmission must be reduced due to the introduction of space-time correlation (STBC). . Therefore, the cascaded structure of channel coding and MIMO space-time hierarchy can benefit from both reliability and efficiency.

[0003] The existing Turbo coding...
