摘要： Disclosed is a transmission device which transmits a systematic code obtained by adding parity bits to information bits. When the code rate of the systematic code is a value in a specific range determined by the decoding characteristic in a case where dummy bits are not inserted, a dummy bit insertion portion inserts dummy bits into the information bits and shifts the decoding characteristic, so that the code rate assumes a value outside a specific range determined by the decoding characteristic after shifting. An encoding portion performs systematic encoding of the information bits into which the dummy bits are inserted, and deletes the dummy bits from the results of the encoding to generate a systematic code, and a rate matching portion, performs rate matching such that the size of the systematic code is equal to a size determined by the physical channel transmission rate, and transmits the systematic code.

摘要： An equalizer device which enables tap coefficient correction accuracy to be improved to enable high-quality adaptive equalization. A tap coefficient filter corrects tap coefficients thereof in accordance with a control signal and equalizes a received signal in which a data signal is multiplexed with a pilot signal, which is a known signal for compensating for variation in reception of the data signal. A training signal setter sets both of the data signal and the pilot signal as a training signal, which indicates an ideal value of equalized output. A tap coefficient corrector obtains an error signal indicative of a differential value between the training signal and a filter output signal which is output from the tap coefficient filter after being equalized, performs an adaptive algorithm operation so as to decrease the error signal, and generates the control signal for correcting the tap coefficients.
