1. A signal detecting method, applied to a base station which is configured to receive an encoded signal, and comprising:

  • obtaining a matched filtering signal;

    determining a filtering matrix used when obtaining the matched filtering signal;

    decomposing the filtering matrix to obtain a principal diagonal matrix and a non-principal diagonal matrix;

    obtaining a parameter matrix and a parameter vector for an iterative calculation according to the principal diagonal matrix, the non-principal diagonal matrix, and the matched filtering signal;

    obtaining an iterative parameter and an iterative initial value according to the parameter matrix and the parameter vector; and

    performing the iterative calculation according to the iterative parameter and the iterative initial value;

    if the number of iterations reaches a preset number, obtaining an iterative final value, and. obtaining an input of a decoder according to the iterative final value, so as to decode the encoded signal and to realize the signal detecting.
