Abstract
Provided is a method for detecting random access signal, and the method includes detecting a peak position of a random access signal in a first preamble section and ignoring the random access signal apart from the peak position for less than a certain distance in a second preamble section adjacent to the first preamble section.
Claims11
A method for detecting a random access signal in a mobile communication system, the method comprising:
- detecting a peak position of a random access signal in a first preamble section;
- identifying a region in a second preamble section adjacent to the first preamble section, the region within a specified distance of the detected peak position;
- and
- ignoring the random access signal apart from the peak position within the region in the second preamble section adjacent to the first preamble section.

A method for detecting a received random access signal in a mobile communication system, the method comprising:
- sequentially indexing a plurality of detection positions of a random access signal;
- calculating an amplitude of the random access signal for each current index value;
- determining which of first and second preamble sections each of the current index value is in;
- determining the current index value of the random access signal having the largest amplitude among the current index values belonging to the first preamble section as a peak index value;
- identifying a region in a second preamble section adjacent to the first preamble section, the region within a specified distance of the detected peak position;
- and
- ignoring a random access signal of a current index value, within the region, among the current index values belonging to the second preamble section.
