Abstract

The present invention provides a multi-user combined detecting method and a device thereof, wherein, the method comprises a step of: at the receiving end of an uplink control channel, detecting a received signal Y through tensor operation for acquiring transmission information of each user, wherein, detecting the received signal through tensor operation for acquiring the transmission information of each user comprises the following processes: performing complex conjugate transpose multiplication on a signal Yant matrix which is obtained from the received signal Y through a first preset sorting role, an initial matrix of the matrix which is composed of transmission information of each user on one time slot and a spread spectrum matrix W of each user; receiving a channel estimation matrix of each user on each receiving antenna; and performing complex conjugate transpose multiplication on the signal Ysym matrix which is obtained from the receiving signal Y through a second preset sorting role, the matrix W and the matrix, thereby obtaining the transmission information of each user on the time slot. The multi-user combined detecting method of the invention settles the problems of large calculation amount and high realization difficulty in the multi-user combined detecting method, thereby reducing calculation amount and reducing realizing difficulty of the method.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a multi-user joint detection method and device. Background technique [0002] In Long Term Evolution (LTE for short), the uplink control channel is divided into formats (format) 1 / 1a / 1b and format 2 / 2a / 2b, wherein the format 1 series is used for scheduling requests (Scheduling Request, referred to as SR) and Acknowledgment (ACK for short) / Non-Acknowledgment (NACK for short), the format 2 series is used for Channel Quality Indication (CQI for short) and ACK / NACK For transmission, a user equipment (User Equipment, UE for short) selects a corresponding format according to a combination of types of signals to be transmitted. An important difference between the Physical Uplink Control Channel (PUCCH for short) and the Physical Uplink Shared Channel (PUSCH for short) is that multiple users simultaneously multiplex the same frequency domain and time domain resources. The receiving e...
