Latest Patents
Haag holds a patent for an "Adaptive Echo Canceller for Full-Duplex Transmission of Data." This invention addresses the challenges associated with echo cancellation in full-duplex carrier modulation transmission systems. The echo canceller utilizes a digital time-domain complex transversal filter with controlled weighting coefficients. It also features an offset that is a submultiple of a Baud period, which is crucial for the effective processing of complex symbols received at the filter's input. The design of this echo canceller is particularly beneficial in systems where the product of the transmission carrier frequency and the Baud period is an integral multiple of l/4, simplifying the digital implementation of the modulator.
