Title:
通信システムにおける受信装置
Document Type and Number:
Japanese Patent JP3892871
Kind Code:
B2
Abstract:
Two correlation signals which are obtained by computing correlations between two reference signals and a reception signal are inputted to a level- 0 cell, the reference signals being generated on the basis of combinations of crosstalk coefficients. A level- 1 soft judgment target signal is produced by using soft judgment target signals that are outputted by two sets of level- 0 cells respectively and, similarly, a level (N+1) cell is formed by using two sets of level-N cells, whereby a soft judgment target signal creation portion with a hierarchical structure is constituted. A judgment unit outputs a soft judgment value of the target subchannel on the basis of the soft judgment target signal that is outputted by the level (N+1) cell, and judges a reception signal.
