摘要： In an error detection method of the present invention, as shown in FIG. 1, target code strings which are inputted in a discontinuous arrangement are subjected to a syndrome operation, and simultaneously, the target code strings which are inputted in a discontinuous arranged are subjected to a first error detection code operation while correcting the inter-data continuity by skipping the data so that the arrangement of the code strings have continuity. Then, error data positions and error data numerical values of the target code strings are calculated on the basis of a syndrome obtained in the syndrome operation, and only the error data position among the target code strings are subjected to a second error detection code operation again on the basis of the error data positions and the error data numerical values. Using the operation result, the operation result by the first error detection code operation is updated, thereby simultaneously performing ECC processing and EDC processing for the target code strings which are inputted in a discontinuous arrangement.

摘要： A receiver employs iterative decoding of packet data, where the packet data represents a data frame encoded with at least two logical dimensions. A logical dimension refers to a layer, or sub-layer, of a layered network architecture. Consequently, a first logical dimension of encoding might refer to error detection in a packet frame at the data link layer, while a second logical dimension of coding might refer to error detection/correction encoding at a physical layer. For example, a data frame might be divided into several packets, each with a corresponding cyclic redundancy check (CRC) value as coding in the first logical dimension, which are then transmitted with a convolutional code as coding in the second logical dimension. The receiver performs iterative decoding in the first and second logical dimensions until either i) all errors are identified and corrected or ii) another type of stopping condition is met.

摘要： There is disclosed a packet transmission apparatus for transmitting in a packet form a transmission unit including a data string arranged so as to divide predetermined data into a plurality of blocks, each block having a fixed length, block information for specifying the block type being added to each block. A DIF data processing circuit generates a transmission header having a new identifier by deleting predetermined redundancy information from the block information belonging to the plurality of blocks based on inputted data string, and then, generates a transmission unit having the generated transmission header. Next, a transmission terminal unit transmits the generated transmission unit by way of a transmission line. In this case, the DIF data processing circuit generates a new identifier by making the information of one block represent the information of the plurality of blocks to generate a transmission header having the generated identifier, or making the information of one block represent the information of an identical block or deleting the redundancy information including at least one of reserved data and invalid data.

摘要： Techniques to implement MBMS services in a wireless communication system. In one aspect, a method is provided for processing data for transmission to a plurality of terminals. Frames of information bits (which may have variable rates) are provided to a buffer implementing a matrix. The matrix is padded with padding bits based on a particular padding scheme to support variable frame rates. The frames are then coded based on a particular block code to provide parity bits. The frame of information bits and the parity bits are then transmitted to the terminals. In another aspect, a method is provided for controlling the transmit power of a data transmission to a plurality of terminals. In accordance with the method, TPC streams are received from the terminals and processed to obtain a stream of joint power control commands used to adjust the transmit power of the data transmission.

摘要： The invention is for a system and method for performing forward error correction on an MPEG-2 transport stream that has optional error correction information embedded within the sport stream. An error correction operation is performed on a super group of packets within the transport stream. The error correction data is inserted into a created trailer group of MPEG-2 compliant transport stream packets having no payload, but only an adaptation field The trailer group packets are optional and therefore can be discarded by a standard MPEG-2 decoder, but can also be used to recover data lost in the transmission of the transport stream. The invention results in a system and method to correct an MPEG-2 transport stream that can be used in any one of the digital video broadcast (DVB) formats, without the need for error correction decoders which are specific to the DVB format.

摘要： A data unit may be organized in error correcting rows and columns. Different error correcting algorithms may be utilized on the rows and columns. As a result, once a double error is identified in a given row, the location of each of the errors along the row may be determined using the column-wise error correcting algorithm. As a result, a single double error may be located and corrected after any other single errors have been corrected. In some embodiments, this may greatly increase the rate of successful error correction.

Analyzing the decoding includes estimating at least one possible error location, storing information related to the at least one possible error location; storing state information, and updating the state information.
