摘要： A decoding apparatus and method is disclosed by which the decoder error occurrence probability is suppressed and a high decoding performance can be achieved. An ABP decoding apparatus diagonalizes a parity check matrix, updates LLR values, decodes the LLR values and then adds a decoded word obtained by the decoding to a decoded word list. The ABP decoding apparatus repeats the decoding procedure as inner repetitive decoding by a predetermined number of times. Further, as the ABP decoding apparatus successively changes initial values for priority ranks of the LLR values, it repeats the inner repetitive decoding as outer repetitive decoding by a predetermined number of times. Then, the ABP decoding apparatus selects an optimum one of the decoded words from within a decoded word list obtained by the repeated inner repetitive decoding. The invention is applied to an error correction system.

摘要： A magnetic recording and/or reproducing apparatus performing efficient decoding to lower a decoding error rate. A magnetic recording and/or reproducing apparatus 50 includes a modulation SISO decoder 63 for modulation decoding data modulation-encoded in a predetermined fashion by a modulation coder 52. In the magnetic recording and/or reproducing apparatus 50, the modulation SISO decoder 63 is a soft input soft output (SISO) type modulation decoder fed with a soft input signal and issuing a soft output signal. The modulation SISO decoder 63 is fed with a trellis soft output signal D64 supplied from a trellis SISO decoder 62 to find a soft decision value for an error correction coding data D52 fed to the modulation coder 52 of the recording system to generate a modulated soft decision signal D65. The modulation SISO decoder 63 routes the so-generated modulated soft decision signal D65 to a downstream side error correction soft decoder 64.

摘要： A receiving apparatus receives a low density parity check (“LCPC”) code and decode the LCPC code to provide for error check capabilities. A bit error rate (“BER”) controlling section is the frequency of the LCPC by using an index comprised of BER conditional information that indicates communication conditions affecting the power consumption at the time of decoding. The frequency is controlled on the basis of a reception interval of the low density parity check code.

摘要： To appropriately express an erasure position of a code by a small-scale, simple-structured circuit, a soft-output decoding circuit (90) in each element decoder includes a received value and a priori probability information selection circuit (154) to select an input to-be-decoded received value TSR and extrinsic information or interleaved data TEXT, whichever is necessary for soft-output decoding. Based on inner erasure position information IERS supplied from an inner erasure information generating circuit (152), the received value and a priori probability information selection circuit (154) replaces a position where no coded output exists due to puncture or the like with a symbol whose likelihood is “0”. That is, the received value and a priori probability information selection circuit (154) outputs information which assures a probability in which a bit corresponding to a position where there is no coded output is “0” or “1” to be “½”.
