Latest Patents

One of Kai Shao's latest patents is titled "Method and system for multi-carrier time division multiplexing modulation/demodulation." This patent outlines a method and system for multi-carrier time-division multiplexing (MC-TDMA) modulation and demodulation. The process involves performing interleaving allocation and an FFT on an input symbol before multi-carrier modulation. A time domain symbol is transformed into a frequency domain symbol signal to undergo MDFT treatment. The sending end utilizes an analyzing filter bank structure, with pre-filtering and an IFFT performed successively on the signal. 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.
