1. A linear system coefficient estimating method, comprising the steps of:

  • (A) (a) inputting, on a basis of M code sequences di (=di1, di2, . . . , diN, where i=1, . . . , M), and M<

    N) each of which has a length N, M inputs Xk (k=1, . . . , M) to a system which has a linear input and output and to which the M inputs Xk (k=1, . . . , M) are to be inputted, the system being represented by
