PROJECTS

Together with my collaborators, Peter Jung and Babak Hassibi, I developed and patented a new non-coherent wireless signaling design, called MOCZ (Modulation On Conjugated Zeros), which allows a reliable and blind communication with ultra-low latency over fast fading and frequency-selective wireless channels. We are looking for project partners in industry and academia to develop implementations in practical scenarios, such as, 5G technologies, massive machine-type-communication, vehicle-to-vehicle/everything communication, and autonomous wireless sensor-networks. For more information please follow our web presence at BMOCZ and Blind Communication and Demodulation.
