Latest Patents

Pan Ju Yan holds a patent for an "Apparatus and methods for demodulating a signal." This invention includes a hard limiter stage that converts an analogue input signal into a two-level signal. The design features a digital down converter and low pass filter stage that transforms the signal into a baseband signal. Additionally, a symbol synchronization stage extracts symbol timing, while an instantaneous phase detector calculates the instantaneous phase of the symbols associated with the input signal. The apparatus is capable of handling various modulation schemes, including pi/4DQPSK, pi/2DBPSK, GMSK, and GFSK. A differential detector determines the phase difference between adjacent symbols, and a coarse frequency offset compensation stage applies a compensation signal to address frequency offsets. Finally, a demapper generates a demodulated output signal after compensation.
