Abstract
The present disclosure provides a method for detecting a random access signal. The method includes: determining a temporary peak detection sequence according to a received time domain random access signal; determining an interference cancellation weight for a frequency domain cyclic shift sequence corresponding to a search window in the temporary peak detection sequence, and performing interference cancellation on the temporary peak detection sequence according to the interference cancellation weight, obtaining a final peak detection sequence; and performing peak detection on the final peak detection sequence. The present disclosure discloses an apparatus and system for detecting a random access signal at the same time. According to the method, the present disclosure can eliminate the deterioration of the leak detection performance and the false detection performance caused by the interference during the random access signal detection, improve the detection accuracy and save resources.
