Latest Patents

Qian Cheng's recent patents include:

1. **Systems and methods for optimizing timing phase in modem devices**: This patent provides an innovative approach for performing necessary phase calculations within a telecommunications system. It focuses on optimizing system performance more efficiently and reducing complexity compared to previous solutions. The method calculates phase delays of the precursor equalizer (EQ) offline, eliminating the need for filling the precursor EQ delay line with a specified number of symbols. The fractional spacing of the precursor EQ allows for simultaneous achievement of both sine and cosine values of the initial phase tone, requiring only 36 quick timing sequence symbols for effective estimation.

2. **Systems and methods for improving timing phase estimation**: This patent outlines a method for performing required phase calculations to enhance telecommunications system performance. It involves estimating the entire decision feedback equalizer (DFE) phase shift based solely on the output of the precursor EQ. This estimation is then utilized to adjust the timing phase accordingly, thereby streamlining the process and further optimizing the system.
