Method, Device and System for Detecting Random Access Signal in Interference Environment |
摘要 |
A method, device and system for detecting a random access signal in an interference environment. The method includes: receiving a time-domain random access signal to obtain a frequency-domain random access signal; obtaining interference cancelling weights 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 obtained interference cancelling weight; and performing peak detection on the frequency-domain random access signal after interference cancelling. The device includes an obtaining module configured to receive a time-domain random access signal to obtain a frequency-domain random access signal; an interference cancellation module configured to calculate interference cancelling weights according to the frequency-domain random access signal and a frequency-domain local cyclic shift sequence, and perform interference cancelling on the frequency-domain random access signal; and a detection module configured to perform peak detection on the frequency-domain random access signal after interference cancelling. |

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. |
