    • There is provided a decoding device capable of rapidly calculating likelihood information while suppressing increase of the processing amount and the circuit size. The device has a backward probability calculation section (112) for performing backward probability calculation by using two processing systems: one for calculating a backward probability betak from a backward probability betak+2 and the other for calculating a backward probability betak-1 from a backward probability betak+ 1. More specifically, when k = 1, the two processing systems calculate the backward probabilities beta1 and beta0 in parallel. The backward probabilities calculated are stored in a storage section (114) in the window unit. Moreover, like the backward probabilities, a forward probability calculation section (113) uses two processing systems for calculating forward probabilities alphak and alphak+1 in parallel. After the forward probabilities are calculated, a likelihood calculation section (115) calculates the likelihood information by using the forward probabilities and the backward probabilities stored in the storage section (114).
    • 提供一种能够在抑制处理量和电路尺寸的增加的同时快速计算似然信息的解码装置。 该装置具有用于通过使用两个处理系统执行向后概率计算的倒退概率计算部分(112):一个用于从后向概率betak + 2计算后向概率betak,另一个用于从后向计算逆向概率betak-1 概率betak + 1.更具体地说,当k = 1时,两个处理系统并行计算反向概率β1和β0。 计算出的反向概率被存储在窗口单元中的存储部分(114)中。 此外,与向后概率一样,前向概率计算部(113)使用两个并行计算前向概率alphak和alphak + 1的处理系统。 在计算前向概率之后,似然度计算部(115)通过使用存储在存储部(114)中的前向概率和后向概率来计算似然信息。
