Latest Patents
One of Ji-Shang Yu's latest patents is titled "One bit differential detector with frequency offset compensation." This invention focuses on a one-bit differential detector for a GMSK signal that operates independently of an offset frequency. The decision signal used by the decision circuit to distinguish between logic '0' and logic '1' is always equal to sin[.DELTA..phi.(T)]. This innovative detector demonstrates improved bit error rate performance compared to prior art. Another significant patent is the "Timing recovery method and system." This apparatus and method are designed for receiving a continuous time pulse amplitude-modulated passband signal. The pulse amplitude modulated signal is periodically sampled by a local clock to generate received samples. A convolution of the received samples and an impulse response function is evaluated at a specific value of a phase difference variable to derive corrected samples. By using a narrow transmission band filter, a periodic signal is derived from the corrected samples, which has a period equal to a symbol period of the pulse-amplitude modulated signal.
