Problems solved by technology

However, because LTE system resource scheduling is both bursty and random in time and frequency, the interference of neighboring cells is also bursty and random.
In this case, the relatively fixed use of the MMSE-IRC algorithm or the MMSE-MRC algorithm cannot achieve optimal performance in various scenarios

Embodiment Construction

[0054] Embodiments of the present invention describe a MIMO detection method and device for an LTE system. Here, the LTE system may include a TDD-LTE system and an FDD-LTE system. Since the MMSE-IRC algorithm performs better than the MMSE-MRC algorithm when there is strong co-frequency adjacent cell interference, it is expected that one of the two receiving algorithms can be adaptively selected according to the intensity of adjacent cell interference. However, it is well known that since resource scheduling in the LTE system is both bursty and random in time and frequency, interference from neighboring cells is also bursty and random. In this case, an important issue is how to respond to bursty and random interference in order to adaptively select MIMO detection algorithms.

[0055] According to the embodiment of the present invention, considering the suddenness and randomness of adjacent cell interference, the interference situation on each resource block (Resource Block, RB...

Abstract

The invention relates to an adaptive algorithm selection MIMO detection method and a device. The MIMO detection method comprises steps that: for a resource unit divided in time domain and frequency domain, an interference correlation matrix is estimated; an adjacent interference state can be determined according to each interference correlation matrix, and a detection algorithm corresponding to each resource unit can be determined; MIMO detection on data of the corresponding resource unit is carried out according to the determined detection algorithm.

Description

technical field [0001] The present invention relates to a long-term research (LTE) system, in particular to a MIMO detection method and device for the LTE system. Background technique [0002] MIMO (Multiple-Input Multiple-Out-put) is an abstract mathematical model used to describe a multi-antenna wireless communication system. Antennas receive and restore the original information. [0003] Because MIMO can greatly increase the data throughput (throughput) and transmission distance of the system without increasing the bandwidth or the total transmission power loss (transmit powerexpenditure), this technology has attracted a lot of attention in recent years and has been widely recognized. Scale application. At present, OFDM (Orthogonal frequency-division multiplexing, Orthogonal Frequency-Division Multiplexing) and MIMO technology are combined in the new generation of mobile communication technology standard - LTE (Long Term Research System). [0004] The MIMO detection al...
