Latest Patents

Wang's latest patents focus on a method and system for multi-carrier time division multiplexing (MC-TDMA) modulation and demodulation. The present disclosure outlines a process where, before multi-carrier modulation is performed on an input symbol, interleaving allocation and an FFT may be executed. A time domain symbol is transformed into a frequency domain symbol signal to perform a MDFT treatment. The sending end adopts an analyzing filter bank structure, and pre-filtering along with an IFFT is performed on the signal successively. A pre-filter is positioned between an NM point FFT and an M point IFFT, which helps in reducing the PAPR value of the system using the symmetry of a coefficient of a filter. Furthermore, a frequency domain symbol signal is allocated to different sub-bands for multi-carrier modulation.
