Interleaver and interleaving method for use in series chain convolutional encoder in a mobile communication system

摘要

Interleaver for [summary] series linear convolution code (SCCC) encoder is disclosed. The interleaver includes a memory having a row region of the n rows and m number of regions, a memory to store the symbols input in series with the region. Interleaver generates the symbols interleaved in the method of random selection of one among the symbols randomly selects one of the row region of the m, stored in the line area, which is the random selection. (SCCC) coder including the component encoder for encoding the symbols are interleaved series from the interleaver linear convolutional code. Component encoders has an effective free distance of the code that has been encoded. In accordance with the present invention, when k is the number of symbols to be input to the series, the memory having a row region of the n row area of ​​the m has m × n ≧ k regions, wherein m is the and is characterized in that is greater than the effective free distance.
