Abstract

The embodiment of the invention relates to a signal-to-noise ratio acquisition device, a method and communication equipment, wherein the signal-to-noise ratio acquisition device is applied in a multiple-input multiple-output system, which comprises a first floor path candidate node acquisition unit which is used for acquiring the candidate node of the first floor path, a other floor path candidate acquisition unit which is used for acquiring the candidate nodes of the other floor paths, a path combination unit which is used for constructing a complete path according to the candidate node of the path first floor and the candidate nodes of the other floor paths, an Eudidean distance acquisition unit which is used for calculating the smallest Eudidean distance in each floor according to the complete path, a signal-to-noise ratio acquisition unit which is used for acquiring the signal-to-noise ratio according to the smallest Eudidean distance of each floor, which is determined by the Eudidean distance acquisition unit, wherein the sum of the candidate nodes of the first floor path is smaller than the sum of the elements in vector sets with different module values in the emit data difference vector set of the first floor path, or the sum of the candidate nodes of at least one floor in the other floor paths is smaller than the sum of the elements in the emit data difference vector set of the path floor.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of communication, and more specifically relate to an apparatus, method and communication device for acquiring a signal-to-noise ratio in a multiple-input multiple-output communication system. Background technique [0002] In a MIMO communication system, a mode called spatial multiplexing (Spatial Multiplexing, SM) can be used to simultaneously transmit multiple data streams on one time-frequency resource, and each data stream is called a layer (Layer). In addition, in a communication system, the receiver usually needs to measure the quality of the received signal, and the signal-to-noise ratio (SNR) is generally used to represent the quality of the received signal. In the MIMO communication system, it is necessary to measure the signal-to-noise ratio on the received data of each layer after demodulation, referred to as post-processing SNR. [0003] In the existing literature, an expres...
