6G: A New Approach to Increasing Data Throughput
White Papers
This whitepaper reviews existing SISO and MIMO case studies as a baseline in order to present a new approach which builds upon them to double the data throughput per sub-THz link. Orthomode Transducers (OMTs) are used in this new approach to combine the vertical and horizontal polarized signals into one dual-polarized signal to double the data throughput relative to a single-polarized transmission. This exploits orthogonal horizontal and vertical polarizations to transmit two independent signals simultaneously on one sub-THz link.
The dual-polarized links are transmitted across a room approximately 8 meters (26.5 feet) using lenses to achieve ~200 Gbps at 285 GHz with two independent single-carrier signals occupying 30 GHz of bandwidth. In addition, the equivalent data throughput of 2X2 MIMO at 142 GHz and 285 GHz is achieved using only one transmit and receive antenna with dual-polarization, doubling the data throughput per sub-THz link.
