Title:
UPLINK RECEIVING AND DETECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2017/211103
Kind Code:
A1
Abstract:
Embodiments of the present application relate to the technical field of wireless communications, and particularly relate to an uplink receiving and detection method and apparatus, used to address the problem of the prior art in which IRC interference suppression schemes have high complexity in large-scale antenna scenarios. In the embodiments of the present application, eigenvector decomposition on a correlation matrix of a total reception interference signal on N sub-carriers is employed to obtain a primary interference characteristic channel matrix, and a channel of a useful signal is combined thereto to form an equalization matrix for joint detection. Equalization detection is performed, according to the equalization matrix, on a received signal to estimate a transmission signal. The present invention enables suppression of co-channel interference simply by determining the primary interference characteristic channel matrix, thus avoiding medium- to high-order matrix inversion computation in conventional IRC detection algorithms, and accordingly achieves suppression of co-channel interference with a low complexity in large-scale antenna scenarios.
