摘要： A turbo decoding device includes a memory unit that stores data in an interleaving process performed in a process of decoding a coded signal encoded with a turbo code and an access unit that accesses the memory unit to read and write the data. The memory unit includes memory circuits and is formed as one memory space by coupling the memory circuits. Furthermore, the memory circuit functions as a first bank configuration by which a first capacity is assigned to each bank or a second bank configuration by which a second capacity is assigned to each bank in accordance with a combination of the memory circuits. Moreover, the access unit selects by which of the first bank configuration and the second bank configuration the memory unit functions in accordance with a communication method of a coded signal and accesses the memory unit in accordance with the selected bank configuration.

摘要： In a transmission apparatus, a comparison unit provides threshold values associated with an amount of data indicating a signal frequency, and compares an input parameter obtained by cumulatively adding a correction amount to the parameter with the threshold values. When the input parameter is within a range defined by the threshold values, a correction unit outputs a value of the input parameter. When the input parameter is out of the defined range, the correction unit outputs an associated one of the threshold values so as to eliminate an amount exceeding or falling short of the defined range, to thereby correct the input parameter. An addition unit detects the correction amount which is an amount of the immediately preceding value of the input parameter exceeding or falling short of the defined range, and cumulatively adds the correction amount to the input parameter used for the comparison of this time.
