Title: Innovations by Hans Oman
Introduction
Hans Oman is a notable inventor based in Lulea, Sweden. He has made significant contributions to the field of telecommunications, particularly in the development of hybrid circuits and synchronization techniques for data transmission.
Latest Patents
Hans Oman holds two patents that showcase his innovative work. The first patent focuses on near-echo suppression, where he developed a hybrid circuit designed to substantially reduce near echo signals. This circuit includes a balanced 2-wire to 4-wire hybrid that interconnects a two-wire receive path and a two-wire transmit path to a two-wire transmission line. The design incorporates a filter in the receive path to eliminate signals transmitted from the D/A converter, making it particularly suitable for Frequency Division Duplex (FDD) and Orthogonal Frequency Division Duplex (OFDD) systems.
The second patent addresses synchronization in Orthogonal Frequency Division Multiplexing (OFDM) systems. It emphasizes the importance of maintaining synchronism between the transmitter and receiver to ensure that each received frame contains data from only a single transmitted frame. The invention utilizes information from an adaptive channel equalizer to control the sampling clock of the receiver, enhancing robustness in synchronization. This technology is especially relevant for ADSL and VDSL modems, facilitating broadband access over copper networks.
