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 method for interleaving input data having a size other than a multiple of 2m (m>1) is disclosed. The method comprises sequentially storing input data in a memory; adding an offset value to the input data size to provide a virtual address having a size of 2m where (m>1); defining a plurality of address generation areas each having a size of 2m m where (m>1), and generating random addresses in the address generation areas; and reading the input data from the memory using the random addresses generated from the address generation areas.

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+x2+x3+x5+x6+x7+x8, g1(x)=1+x +x3+x4+x7+x8, and g2(x)=1+x+x2+x5+x8, 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.
