Latest Patents

Hahn's patent, titled "Symbol Synchronizer for MPSK Signals," showcases his innovative approach to signal detection. This symbol synchronizer is designed for apparatus that detects MPSK signals, offering complex sampled data that describes keying signal phases. The invention features a system where timing for resampling is precisely controlled, allowing for resolution finer than the time between successive complex data samples.

The technology revolves around the use of a first digital controlled oscillator to recover the MPSK baseband signal at a specified sampling frequency. Subsequently, the MPSK signal is processed to yield a sampled data envelope description, which may be equal to or derived from the initial frequency. This sampled data is filtered to produce a locking signal for a second digital controlled oscillator, which generates a digitally sampled description of a sawtooth waveform. This waveform, fundamental to keying operations, enables accurate resampling of the MPSK signal, providing complex samples that are phase-locked for effective decoding.
