<P>PROBLEM TO BE SOLVED: To provide a demodulator capable of realizing high accuracy when generating a delay profile by using the received data of only a single shaft, a demodulation method, and a program. <P>SOLUTION: The demodulator is composed by including a delay profile recalculation means for executing calculation to a delay profile which is calculated by using the single shaft only, in the received data by using a delay profile value in a calculation range after making one specific symbol and some symbols before and after the one specific symbol as the calculation range, and also, for outputting the calculation results as a delay profile value of the specific symbol. Electric power regarding the symbol of the peak can be calculated by calculating the sum of squares of a correlation value over several symbols before and after the peak. Consequently, the delay profile can be made highly accurate by removing effects of phase inclinations. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
