Latest Patents

Zhuang's latest patents include a method and system for multi-carrier time division multiplexing modulation/demodulation. This patent outlines a process where, before multi-carrier modulation is performed on an input symbol, interleaving allocation and an FFT may be executed. The method transforms a time domain symbol into a frequency domain symbol signal to perform a MDFT treatment. The sending end utilizes an analyzing filter bank structure, and the signal undergoes pre-filtering and an IFFT successively. A pre-filter is strategically positioned between an NM point FFT and an M point IFFT, which helps reduce the PAPR value of the system by leveraging the symmetry of a filter's coefficient. Additionally, the frequency domain symbol signal is allocated to different sub-bands for effective multi-carrier modulation.
