Benefits of technology
This patent describes a device and method for testing a MIMO bolt-on device using a MIMO channel emulator. This device includes a multi-channel receiver, a coupler, a micro-controller, and a switch device. The method involves comparing signals from multiple channels and identifying the channel with the highest signal-to-noise ratio (SNR) using the micro-controller. The switch device is then used to select the antenna with the highest SNR for connection to the MIMO radio. The technical effect of this patent is to provide a reliable and efficient way to test MIMO devices in a cost-effective and efficient manner.
Problems solved by technology
However, in a contended environment, the strongest input signal that an antenna corresponds may be a jamming signal.
Accordingly, instead of a desired antenna, the conventional antenna selection scheme may select an antenna corresponding to the strongest jamming signal for transmission, which deteriorates the quality of wireless communications between the receiver and the transmitter.

A multiple-input and multiple-output (MIMO) bolt-on device for a single-input and single-output (SISO) radio, a MIMO channel emulator for testing the MIMO bolt-on device, and a MIMO channel emulation method are provided. The MIMO bolt-on device includes: a plurality of antennas, a multi-channel receiver, a plurality of couplers, a micro-controller, and a switch device. The multi-channel receiver includes a plurality of channels for signal transmission. Each coupler is configured to couple the multi-channel receiver with one of the plurality of antennas. The micro-controller is coupled to the multi-channel receiver to compare signals from the plurality of channels, thereby identifying a channel with a highest signal-to-noise (SNR) among the plurality of channels. The switch device is coupled to the micro-controller and configured to select an antenna corresponding to the channel with the highest SNR among the plurality of antennas for a connection between a selected antenna and the SISO radio.
Description
GOVERNMENT RIGHTS[0001]This invention was made with Government support under Agreement No. W15QKN-15-9-1004, awarded by the ACC-NJ to the NSC. The U.S. Government has certain rights in this invention.FIELD OF THE DISCLOSURE[0002]The present disclosure generally relates to the technical field of multiple-input and multiple-output (MIMO) technology and, more particularly, to a MIMO bolt-on device for a single-input and single-output (SISO) radio, a MIMO channel emulator for testing the MIMO bolt-on device, and a MIMO channel emulation method.BACKGROUND[0003]Radio channel emulators have been used for many years and are essential tools for signal propagation testing to emulate the radio propagation based on pre-defined environmental conditions. Currently, most channel emulators are designed for low spectral-efficient single-input and single-output (SISO) communication system.[0004]To enhance the performance of the wireless radio transmission, the multi-input and multi-output (MIMO) tech...
