1. A method for detecting a random access signal in an interference environment, comprising:

  • receiving a time-domain random access signal to obtain a frequency-domain random access signal;

    obtaining interference cancelling weights respectively according to the frequency-domain random access signal and a frequency-domain local cyclic shift sequence, and performing interference cancelling on the frequency-domain random access signal with the obtained interference cancelling weights; and

    performing peak detection on the frequency-domain random access signal on which interference cancelling has been performed.
