Abstract

A shaped beam and multiple-input-multiple-output multi-antenna reuse switching system comprises a mode judging module, a switching module, a blocking factor (BF) transmitting module, a multiple-input-multiple-output (MIMO) multi-antenna reuse module, wherein the mode judging module used for judging whether a most suitable transmitting mode for a user is the shaped beam mode or the multiple-input-multiple-output multi-antenna reuse mode according to the switching algorithm, the switching module is used for deciding whether the shaped beam mode or the multiple-input-multiple-output multi-antenna reuse mode is adopted to transmit data information according to a result of mode judging modules, the BF transmitting mode is connected with the switching mode, and used for multiplying data with weight components of corresponding antenna and then retransmitting the data, and the MIMO multi-antenna reuse module is connected with the switching mode and used for carrying out MIMO code on the data, and transmitting the data after the MIMO code. The data information is transmitted in an electromagnetic mode outwards based on metamaterials composed of a plurality of metamaterial antenna units. The metamaterial array antennas are adopted to receive or transmit signals, and signal interference noise ratio of an entire system is improved, and interference of receiving or transmitting of environment signals is reduced.

Description

technical field [0001] The present invention relates to a wireless communication system, in particular to a beamforming (BF for short) and Multiple Input Multiple Output (MIMO for short) multi-antenna multiplexing switching system based on a metamaterial array antenna. Background technique [0002] The beamforming technology is to use the antenna array to weight the antenna units on each array through advanced signal processing algorithms, so that the array antenna is aligned in the direction of the useful signal in real time. Form a zero point in the interference direction to suppress the interference signal, thereby improving the signal-to-interference-noise ratio, improving the system link quality, and increasing the coverage of the system. [0003] Multiple-input multiple-output technology is a communication system in which multiple antennas are installed at the transmitting end and the receiving end, and it is mainly divided into two categories. One is that when there ...
