Abstract:
1. A method for detection in cell random access, comprising: in a Long Term Evolution (LTE) protocol, extending an original format used for a random access procedure to change a cyclic prefix range defined by the original format, to obtain an enhanced format used for the random access procedure; in a process of extracting a time-domain signal of a random access channel, extracting and splitting input data into time-domain antenna data in the original format and time-domain antenna data in the enhanced format, and performing signal extraction processing respectively on the time-domain antenna data in the original format and the time-domain antenna data in the enhanced format; and in a process of detection, detecting the time-domain antenna data in the original format and the time-domain antenna data in the enhanced format after the signal extraction processing to obtain detection information, wherein performing the signal extraction processing respectively on the time-domain antenna data in the original format and the time-domain antenna data in the enhanced format respectively comprises: performing filter extraction, two-dimensional Fourier transform (
