    摘要: An iterative decoder with a gain controller in a mobile communication system. In the iterative decoder, a first component decoder receives a first extrinsic information signal, a first parity signal, and a systematic code signal, decodes the systematic code signal out of the received signals, and generates a primary decoded signal including a second extrinsic information component. Here, the first and second extrinsic information signals remove noise in the input signals to the first and second component decoders. A second component decoder receives the primary decoded signal from the first component decoder and a second parity signal, decodes the decoded signal out of the received signals, and generates a secondary decoded signal and the first extrinsic information signal. One or more gain controllers are connected between the first and second component decoders, for attenuating either or both the first and second extrinsic information signals.

    摘要: A device and method for matching a rate of channel-encoded symbols in a data communication system. The rate matching device and method can be applied to a data communication system which uses one or both of a non-systematic code (such as a convolution code or a linear function code) and a systematic code (such as a turbo code). The rate matching device includes a plurality of rate matching functions, the number of the rate matching functions being equal to a reciprocal of a coding rate of a channel encoder. The rate matching device can rate match the symbols encoded with a non-systematic code or the symbols encoded with a systematic code, by changing initial parameters including the number of input symbols, the number of output symbols, and the puncturing/repetition pattern determining parameter.

    摘要: Disclosed is an apparatus for transmitting a sequence of information bits and sequences of parity bits to a receiver in a transmitter of an HARQ transmission system. A turbo encoder receives a sequence of L information bits, and generates the sequence of information bits and M sequences of L parity bits for the information bits, wherein M is determined depending on a transmission code rate. A redundancy selector includes the sequence of information bits in an initial data block during initial transmission, and uniformly includes non-transmitted parity bits out of parity bits provided from each sequence of the parity bits in a retransmission data block upon every receipt of a retransmission request from the receiver.

    摘要: A convolutional encoding device and method in a digital system. According to an embodiment of the present invention, a convolutional encoding device has a convolutional encoder and a puncturer. The convolutional encoder generates a subgroup of a first, a second and a third encoded symbols for each input bit using generator polynomials including g0(x) = 1 + x + x + x + x + `x + x , g1(x) = 1 + x + x + x + x + x , and g2(x) = 1 + x + x + x + x , for inputting input bits to generate a symbol group of three subgroups for three successive input bits, and for generating a stream of the symbol groups. A symbol puncturer punctures the first symbol of one of three subgroups in each symbol group generated from the convolutional encoder.

    摘要: A transmitting device in a mobile communication system is disclosed. In the transmitting device, an encoder receives an information bit stream in a frame, which is as long as an integer multiple of a predetermined value, and generates an information symbol, a first parity symbol, and a second parity symbol by encoding each information bit. An interleaver sequentially arranges the information symbols and the first and second parity symbols by rows in an array with an integer number of rows and an integer number of columns. The interleaver reorders the columns in the array according to a predetermined rule. The interleaver further outputs a plurality of radio frames in a stream, by reading the symbols by going down each column, starting at the leftmost column and proceeding right. Each radio frame has a predetermined size. A demultiplexer demultiplexes each of the radio frames received from the interleaver into a stream of information symbols, a stream of first parity symbols, and a stream of second parity symbols. A rate matcher bypasses the stream of information symbols and punctures the streams of the first and second parity symbols for rate matching.
