Embodiment

[0084] This embodiment integrates the MIMO multi-antenna signal transmission and detection technology based on artificial intelligence and compressed sensing proposed in this application, and describes specific implementation steps of the present invention in detail with examples.

[0085] First, the information source is generated by using a random number generator 101 to generate a 0,1 bit sequence.

[0086] Modulation is to modulate bit data, including BPSK, QPSK, 16QAM and 64QAM, etc.

[0087] This embodiment uses BPSK modulation as an example for illustration.

[0088] according to figure 2 The processing flow of the shown signal at the device transmitting end 1 and the device receiving end 2, the specific steps are as follows:

[0089] S1: Signal processing of device transmitter 1.

[0090] S11: Use the random number generator 101 to generate a 0,1 bit sequence to form the original data.

[0091] S12: Generate signal x after BPSK modulation. The sending data of eac...

Abstract

The invention relates to an MIMO multi-antenna signal transmission and detection device based on artificial intelligence. The device comprises the components of a sparse module which performs sparse representation on an original signal by means of a first neural network module; a compression multiplexing module which performs compression dimension reduction processing on the signal after sparse representation; and a device receiving end which is used for processing the received signal for realizing target signal reconstruction, wherein the device further includes a demultiplexing module, wherein the demultiplexing module is configured at the device receiving end and utilizes a compressed sensing reconstruction algorithm for solving a sparse representation vector from a low-dimensional signal and reconstructing the received signal by means of a second neural network model for obtaining the original signal x.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to an artificial intelligence-based MIMO multi-antenna signal transmission and detection technology. Background technique [0002] The research and development of communication technology can be regarded as the common wealth of all mankind, but the global communication standard it brings is not only a technical standard, but also related to industrial development and national strategy. China has experienced nothing in the 2G era, debuted on the stage in the 3G era, and accompanied it in the 4G era. In the 5G era, our goal is to be a heavyweight player, which will greatly promote the development of China's communications industry and the development of the entire national economy. [0003] MIMO (Multiple-Input Multiple-Output), also known as multiple-input multiple-output system, refers to a communication system that uses multiple antennas at the transmitter and device r...
