Claim 17:
18. A reception method, comprising:
obtaining one or more reception signals that include a first converted signal z1(i) and a second converted signal z2(i), where i is an integer greater than or equal to 0,
wherein the first converted signal z1(i) and the second converted signal z2(i) are generated by multiplying, (
