Latest Patents

Ferrad's latest patents include an "Apparatus for estimating the frequency difference existing between the carrier frequency of a digital signal and the frequency of a receiver local oscillator." This apparatus is designed to estimate the frequency difference between the carrier frequency of a received digital signal and the frequency of a local oscillator in a receiver. The receiver performs quadrature demodulation on the received signal. The apparatus features a detector for noise level detection, a processor for computing discrete Fourier transforms, a summer for summing energy levels, a subtractor for noise level subtraction, and a comparator for delivering an estimate of the frequency difference.

Another significant patent is the "System for detecting the presence of a digital signal carrier wave, and a receiver including such a system." This invention relates to a system that detects the presence of a carrier wave in a digital signal at a specific frequency. It delivers baseband samples of the digital signal at each symbol time and includes a timing estimator and a detector that generates a detection signal when a certain threshold is reached. This invention is particularly applicable to receivers of signals transmitted in DTMA mode.
