Application of MIMO Techniques in Macroscopic Air-based Molecular Communication

In this contribution, an air-based macroscopic 2 x 2 multiple-input multiple-output (MIMO) molecular communication testbed using fluorescent dyes is presented and the application of MIMO techniques is investigated. It is demonstrated that the data rate can be doubled using spatial multiplexing. Using repetition MIMO coding and Alamouti-type coding, a spatial diversity/array gain can be achieved, resulting in error-free transmission over the entire transmission distance of the testbed.
