IPC: G10L19/00
Filed: 1998-08-31
Abstract: PURPOSE: A method for determining data rate of variable-rate transmission data is provided to perform pre-decoding with a receivable data rate and then determine data rate of a received data using quality information of pre-decoded data such as symbol error rate. CONSTITUTION: The method first detects quality information of data which is pre-processed by a pre-processor(205, 210, 215) and pre-decoded by a pre-decoder(201, 206, 211, 216) at respective corresponding data rates. Thereafter, based on the quality information, data rate of received data is presumed. Selectively, the pre-decoded data can be again encoded by a encoder(202, 207, 212, 217) to output a first quality information of data. At this time, the first quality information of data is compared with the received data by a comparator(203, 208, 213, 218). Then, a number of error when the first quality information of data is different from the received data is counted by a counter(204, 209, 214, 219) and error metric for a first data rate is output. Thereby, the decoding speed of the received data and determining speed of data rate are both increase.
