Problems solved by technology

For the "CIR split method", since the channel impulse response is split, a non-real system matrix A is obtained based on the non-real channel impulse response, and then a non-real system matrix A is obtained based on the non-real system matrix A matrix A H A, so that the estimate of the transmitted data symbol sequence obtained by the above formula (3) with large distortion

Abstract

The embodiment of the invention provides a signal joint inspection method and device. The method comprises calculating a system matrix based on channel impulse responses related to each code channel and complex spreading codes of channelized codes; calculating a correlation matrix based on the system matrix and a transpose of the system matrix; removing a sub-block the coherent element of which is smaller than a preset value from the correlation matrix to obtain a converted correlation matrix; carrying out joint inspection of received signals by means of the converted correlation matrix to obtain expected detection signals. According to the invention, detection signals with less distortions can be obtained. Furthermore, when the joint inspection is carried out, only one matrix inversion calculation is needed, and therefore the calculation complexity is reduced.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 61 / 858,894, filed July 26, 2013, and U.S. Provisional Application No. 61 / 858,920, filed July 26, 2013, the disclosures of which are incorporated by reference All incorporated herein. technical field [0003] Various embodiments of the present invention relate to the technical field of wireless communication, and more specifically relate to a method and device for joint detection of signals. Background technique [0004] Time Division Synchronous Code Division Multiple Access (TD-SCDMA) system is a synchronous system, and the time of each base station is synchronized. A user equipment (UE) may receive signals from multiple cells including a serving cell and a neighboring cell, and a base station may also receive signals from a UE in a serving cell and a UE in a neighboring cell, wherein the signal of a neighboring cell belongs to interference. Sinc...
