摘要:
Coding section 205 recodes decoded data stored in decoded data storage section 204, data conversion section 206 converts data “0” and “1” output from coding section 205 to “1” and “−1” respectively, sum-of-product calculation section 207 multiplies the data output from data conversion section 206 by the demodulated data (soft decision value) stored in demodulated data storage section 201 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 208 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.
