- Abstract
- A random access preamble detection method of a base station includes removing a cyclic prefix (CP) from a received signal, detecting a plurality of first symbols corresponding to a plurality of first subcarriers included in an uplink available resource from the received signal with the CP removed, measuring reception power of the first symbol corresponding to each of a plurality of second subcarriers allocated to a random access channel among the plurality of first subcarriers, accumulating reception power with respect to each of the plurality of second subcarriers according to a predetermined frequency hopping pattern, and upon completely accumulating reception power according to the frequency hopping pattern, detecting a preamble sequence using each accumulated value of reception power of each of the plurality of second subcarriers.
