Latest Patents
One of Backstrom's latest patents is for a diversity radio receiver automatic frequency control. This invention employs antenna diversity, utilizing multiple antennas and a local oscillator. Individual error signals are derived from each antenna's received signals, which are then combined to create a more reliable error signal. This combined signal enhances the performance of the automatic frequency control circuit, ultimately improving radio reception quality by reducing the effects of fading.
Another significant patent is related to equalizer training in a radiotelephone system. This invention enhances the reception of transmissions by training the equalizer using a synchronization portion of the transmission that has a data pattern chosen for its correlation properties. The equalizer is retrained using a different portion of the transmission, which may include a digital verification color code. This method increases reception quality without adding to the transmission overhead.
