摘要： A receiving apparatus includes: an LDPC decoding device configured such that when an LDPC-coded data signal, LDPC representing Low Density Parity Check, and an LDPC-coded transmission control signal are transmitted in multiplexed fashion, the LDPC decoding device can decode both the data signal and the transmission control signal; a holding device configured to be located upstream of the LDPC decoding device and to hold at least the transmission control signal upon receipt of the data signal and the transmission control signal; and a control device configured to control the LDPC decoding device to decode the data signal while the transmission control signal is being accumulated in the holding device and to interrupt the current decoding so as to control the LDPC decoding device to decode the transmission control signal when the transmission control signal has been accumulated in the holding device.

摘要： In a vessel (2) to which waste liquid (11) which contains ink pigment, water and cleaning liquid used in a printer is supplied, a metal electrode plate (30a, 30b) which allows the waste liquid (11) to flow therethrough is disposed to partition the inside of the vessel (2) into a first region (a) and a second region (b). A high voltage from a high-voltage power supply (7) is applied to the metal electrode plate (30a, 30b) while a grounding electrode (20) is connected to the first chamber (a) to generate an electrostatic field between the metal electrode plate (30a, 30b) and the grounding electrode (20) so that the water and the ink pigment are electrostatically agglomerated from the waste liquid (11) making use of electrophoresis of the ink pigment by the electrostatic field thereby to separate the waste liquid in the first region (a) into the cleaning liquid, water and ink pigment.

摘要： The present invention provides a decoding device for decoding an LDPC (Low Density Parity Check) code. The decoding device include: a first operation unit for performing a check node operation for decoding the LDPC code, the operation including an operation of a nonlinear function and an operation of an inverse function of the nonlinear function; and a second operation unit for performing a variable node operation for decoding the LDPC code. The first operation unit includes a first converting unit for converting a first quantization value assigned to a numerical value into a second quantization value representing a numerical value with a higher precision than the first quantization value, and a second converting unit for converting the second quantization value into the first quantization value. In processing performed as the check node operation and the variable node operation, the first operation unit and the second operation unit use the second quantization value in processing from after the operation of the nonlinear function to the operation of the inverse function, and use the first quantization value in the other processing.
