Latest Patents

Matsusaki holds a patent for an encoder, decoder, transmission device, and reception device. This invention provides a transmission device and reception device for digital data that exhibit excellent resistance to noise. The encoder applies Low-Density Parity-Check (LDPC) encoding to digital data using a unique check matrix for each code rate. This is achieved by utilizing a check matrix initial value table established in advance for each code rate at a code length of 44880 bits. The design allocates entries of a partial matrix corresponding to an information length appropriate for a code rate of 93/120 in the column direction over a cycle of 374 columns. The demodulator included in the reception device decodes digital data encoded by the encoder.
