Wireless communications equipments with function of detecting random access signal, wireless communications systems with function of detecting random access signal and method of random access signal detection
A wireless communication equipment includes receive processing and transmit processing. The receive processing includes a Fourier transform unit that transforms all received signals to frequency region signals by Fourier transform. A demodulation unit demodulates the received signals from the Fourier-transformed frequency region signals. A random access detection unit that monitors signals in frequency regions of random access signals of the Fourier-transformed frequency region signals, and detects that the random access signals are received, by a change pattern of the signals in the frequency regions of random access signals in one transmission time interval.
