PROBLEM TO BE SOLVED: To provide a multi-path estimation device, etc. with small hardware resources and software resources.SOLUTION: A register 330 generates a replica code E advancing to a prompt replica code P by 0.05 chip, a replica code L delayed by 0.05 chip, a replica code VE advancing by 0.1 chip and a replica code VL delayed by 0.1 chip. A correlation processing section 30 generates five correlation values out of correlation processing of the replica codes VE,E,P,L,VL and a C/A code. An estimation section 400 estimates about a multi-path signal from a coefficient value of a linear term of a polynomial of the fourth degree approximated by each phase offset value (-0.1,-0.05,0,0.05,0.1) and each correlation value. |
