Abstract
Coding section recodes decoded data stored in decoded data storage section , data conversion section converts data “0” and “1” output from coding section to “1” and “−1” respectively, sum-of-product calculation section multiplies the data output from data conversion section by the demodulated data (soft decision value) stored in demodulated data storage section and then calculates the sum of the products for 1 TTI and stores the sum-of-product result for each data rate, data rate decision section decides the data rate corresponding to a maximum value of the sum-of-product results as the data rate of the demodulated data. This makes it possible to improve the accuracy of data rate decision and reduce decoding errors of a received signal.
