| abstract | (57) [Summary] To decode an arbitrary code with a simple configuration. In a soft output decoding circuit in an element decoder, a soft output calculation circuit for calculating a log soft output Iλ includes a log likelihood Iα and a log likelihood Iγ corresponding to each branch on a trellis. And the log likelihood Iβ are calculated, an enable signal indicating the input of each branch is generated, and based on the enable signal, an operation analogous to a winning game is performed to calculate a log soft output Iλ. . Specifically, log -Sum arithmetic circuit 312 log-sum operation cell circuit 325 1 of 1, ..., 325 31, respectively, of the data AGB 32 lines entered inputs the data AGB of two systems, these two systems Data A Input two enable signals EN corresponding to GB, Data AGB is selectively output based on the enable signal EN, and a cumulative addition operation of log-sum operation according to the input is realized. |
