He has made significant contributions to the field of telecommunications, particularly in the development of multi-carrier transmission systems. His innovative work has led to the filing of a patent that showcases his expertise and creativity in this area.
Latest Patents
Thomas holds a patent for a multi-carrier transmission system utilizing Discrete Multitone (DMT) technology. This system is designed to recover a receiver sample and clock from a reserved pilot carrier, which maintains a fixed phase. The sampling clock oscillator in the receiver is phase locked to this pilot carrier, ensuring accurate synchronization. Multi-carrier receivers, such as DMT receivers, typically incorporate an FFT processor, which provides a complex number representing the pilot carrier from its output. In cases where an FFT processor is unavailable, a one-frequency DFT processor can be employed to generate a complex estimate of the pilot carrier. In a DMT system, frame synchronization is managed separately from sampling clock synchronization, although both processes are closely related and require frame synchronization to be established before sampling clock synchronization can occur.
