Abstract: Data D28 of 384 symbols each (fundamental data) corresponding to a transmission rate on a communication line is sequentially obtained by de-interleaving received data. A de-repetition circuit 212 sequentially outputs four kinds of data D29 to D32 of 384 symbols, 192 symbols, 96 symbols and 48 symbols, including data transfer rates of approximately 9600 bps, approximately 4800 bps, approximately 2400 bps and approximately 1200 bps in response to the data D28 of 384 symbols each. In that case, the data D28 is outputted as the data D29 as it is. At that very moment, a hold circuit 222 and an adder 223 are used to generate data whose data amount is ½ times the data amount from the data D28 as the next outputted data D30, and the data thus generated is written in a memory 213. When data D30, D31 are also outputted, data D31, D32 are respectively generated in the same way. Thus, it is sufficient that the received data of 384 symbols each might be de-interleaved once.

Abstract: A Viterbi decoding apparatus sets the initial path metric value of each state to a value weighted based on the initial value of a convolutional encoder, and decodes a data string one bit by one bit whenever performing tracing-back for one step with a fixed state determined based on a value of a tail bit as a start-point state when a path metric operation has reached the final operation. Moreover, the Viterbi decoding apparatus selects a maximum-likelihood state out of prospective states determined based on the value of the tail bit and performs tracing-back, until the path metric operation reaches the final operation after it has exceeded the number of data strings. Thus, it is possible to improve the decoding accuracy and the decoding speed.

Abstract: An ACS calculation is performed with received data and when the punctured process has not been performed, a trace-back process is performed in a loop. In this case, a punctured pattern of which data received at one time point, in those at three time points that have not been punctured, is used. Thus, the trace-back process is performed for the data at the time point. With the trace-back process performed once, decoded data at three time points including punctured data at two time points is generated. Since the trace-back process is not performed with punctured data as the start point, an error of decoded data can be prevented or suppressed.
