Latest Patents
One of his key patents is titled "Amplify-and-forward relaying in communication systems." This patent describes an improved method for amplify-and-forward relaying in a communication network. The invention includes an example network comprising multiple single-antenna mobile stations, a multi-antenna relay station, and a multi-antenna base station. The technology enables bi-directional communication with enhanced transmission efficiency through suitable transmit/receive processing at the relay station. This approach addresses the drawbacks of current relaying techniques. The patent discloses linear transmit and receive processing matrices, demonstrating that the number of antennas at the relay station and the base station can be substantially the same without compromising network capacity. This innovation closely matches the performance of existing techniques that require the relay station to have twice as many antennas as the base station, effectively optimizing performance for both low and high signal-to-noise ratios.
