Latest Patents

Hamid Jafakhani holds a patent for a "Space-Time-State Block Coded MIMO Communication System Using Reconfigurable Antennas." This invention utilizes one or more antennas that operate according to a Space-Time-State Block Code (STS-BC) to facilitate channel coding of signals transmitted wirelessly between communication devices. The reconfigurable nature of the antennas allows them to adapt to different radiation states, which can be viewed as a form of three-dimensional channel coding. This approach not only achieves time diversity in signal transmission but also incorporates state diversity by modifying the characteristics of the antennas. The STS-BC can function in an open-loop configuration, eliminating the need for feedback from the receiving device, although feedback can be utilized for adaptive modifications.
