PROBLEM TO BE SOLVED: To surely perform channel estimation even when a channel that is about to be received is affected by fading. SOLUTION: A desired channel is scanned and frequency correction burst is detected (step 101). Synchronization establishment processing of time and frequency is performed by using the frequency correction burst (step 102), and synchronous burst is received (step 103). A channel estimated value is calculated by performing a cross correlation operation between a receiving training sequence during synchronous burst and one specific part of a predicted training sequence (step 104). A frequency error estimated value is calculated from the channel estimated value, and the frequency error of the frequency correction burst is corrected on the basis of the frequency error estimated value (step 105). The equalization of the received synchronous burst is performed (step 106). Synchronous establishment processing at precise time and in a precise frequency is performed by using a symbol undergoing frequency correction (step 107). |
