摘要： A disk drive is disclosed comprising a disk and a head actuated over the disk. The disk comprises a plurality of tracks, wherein each track comprises a plurality of data sectors including a parity sector, the parity sector comprising at least a P0 parity codeword and a P1 parity codeword. A plurality of data sectors are read from the disk (including the parity sector) to generate a plurality of data codewords CW0-CWn. The data sectors are decoded using an error correction code (ECC) decoder. When a single data codeword in CW0-CWn is unrecoverable using the ECC decoder, the single data codeword is recovered using the P0 parity codeword. When two data codewords in CW0-CWn are unrecoverable using the ECC decoder, the two data codewords are recovered using the P0 and P1 parity codewords.

摘要： The present invention provides methods and systems for decoding a data burst in a communication system. A data burst, including a plurality of forward error correction (FEC) blocks, is received. At least one FEC block of the data burst is decoded. Thereafter, it is detected if one or more errors are present in the at least one FEC block of the data burst. Upon detecting one or more errors in the at least one FEC block, the method halts the decoding of the data burst. In response to detecting the one or more errors, a retransmitted data burst corresponding to the data burst is received. One or more FEC blocks of the data burst may be combined with corresponding one or more FEC blocks of the retransmitted data burst. The one or more FEC blocks of the data burst includes the at least one FEC block that had the one or more errors detected as present. Thereafter, the decoding of the retransmitted data burst is commenced starting from the at least one FEC block that had the one or more errors detected as present in the previous transmission.

摘要： Data bits to be encoded are split into a plurality of subgroups. Each subgroup is encoded separately to generate a corresponding codeword. Selected subsets are removed from the corresponding codewords, leaving behind shortened codewords, and are many-to-one transformed to condensed bits. The final codeword is a combination of the shortened codewords and the condensed bits. A representation of the final codeword is decoded by being partitioned to a selected subset and a plurality of remaining subsets. Each remaining subset is decoded separately. If one of the decodings fails, the remaining subset whose decoding failed is decoded at least in part according to the selected subset. If the encoding and decoding are systematic then the selected subsets are of parity bits.

摘要： An ECC controller for a flash memory device storing M-bit data (M: a positive integer equal to or greater than 2) includes an encoder and a decoder. The encoder generates first ECC data for input data to be stored in the flash memory device using a first error correction scheme and generates second ECC data for the input data using a second error correction scheme. The input data, the first ECC data, and the second ECC data are stored in the flash memory device. The decoder calculates the number of errors in data read from the flash memory device and corrects the errors in the read data using one of the first ECC data and the second ECC data selectively based on the number of the errors.

摘要： A Method and System for Utilization of an Outer Decoder in a Broadcast Services Communication System is described. An outer decoder and an inner decoder encode a block of information to be transmitted, to improve protection by adding redundancy. The redundancy permits decoding of the information from less than a complete encoded block of information. Consequently, the receiving station determines when sufficient amount of information for successful decoding has been received, and utilizes the time remaining before the next block of information arrives to perform other activities, e.g., hard handoff on a broadcast channel, inter-frequency hard handoff, and other activities. Alternatively, the receiving station can cease reception, thus decrease power consumption. Furthermore, part of the information block may be utilized for transmission of signaling information.
