Latest Patents
Among his latest patents is a signal processing device and transmission device. This device includes a memory and a processor that compensates for an electric field signal representing an electric field component in an optical signal. It addresses the optical frequency offset between light sources on the transmission and reception sides of the optical signal. The processor calculates an estimated value of the optical frequency offset and generates multiple candidates for the compensation value based on this estimation. It then selects an initial value of the compensation based on the power of the optical signal.
Another notable patent is for an adaptive equalizer, optical receiver, and optical transmission system. This adaptive equalizer features a sample buffer that temporarily stores data obtained through fractional sampling. The processor specifies the position of a training sequence in the data and calculates an initial value of a tap coefficient set to a tap of an adaptive equalization filter based on the specified training sequence.
