Problems solved by technology

[0017] It can be seen from equations (5) and (6) that although the above-mentioned joint detection device does not need to directly calculate the inverse matrix of the correlation matrix R, it needs to perform a square root operation, so the amount of calculation is still very large
When the above-mentioned joint detection device is used on user equipment such as mobile phones, there will be problems of slow operation response of user equipment and large power consumption

Abstract

The invention discloses a combined detection method, a device for communication equipment and the communication equipment. The combined detection method includes computing a matched filter function of the received signal and a correlation matrix related to the transmission channel by useful signal included in the received signal and channel estimation result of the transmission channel; converting correlation matrices into forms of lower triangular matrices, diagonal matrices, and products of associated matrices of lower triangular matrices by LDLH decomposition of the correlation matrices; and computing the useful signal using lower triangular matrices, diagonal matrices, associated matrices of the lower triangular matrices and the computation result of the matching filtering function.

Description

technical field [0001] The present invention relates to the field of wireless communication, and more particularly relates to a joint detection method, device and communication equipment for communication equipment that can be used in a time division synchronous code division multiple access system. Background technique [0002] With the development of wireless communication technology, wireless resources are becoming increasingly tense. The Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system, one of the mainstream standards of the third generation mobile communication (3G), is no exception. In order to improve the spectrum utilization rate, the TD-SCDMA system adopts the same-frequency networking solution, but it causes the same-frequency interference. There are two main types of co-channel interference: 1) intra-cell interference, also known as multiple access interference (MAI), that is, interference caused by other user signals within the same cell...
