Patent ID: 8837417

Claim:
An apparatus for transmitting a Hopping Pilot Beacon (HPB) in a communication system, the apparatus comprising: switches, wherein a number of the switches corresponds to a number of Frequency Assignments (FAs) used in the communication system; a Demultiplexer (DEMUX) for connecting one of a plurality of first input lines, which provides an HPB signal to each of the switches, with a corresponding one of a plurality of output lines of the switches; an HPB Multiplexer (MUX) control block for receiving the HPB signal and information of the HPB signal from an upper board, acquiring frequency information from the HPB signal, selecting a switch, from among the switches, having a second input line through which a frequency, corresponding to a particular FA from among the FAs, is input, and controlling the DEMUX to connect a first input line of the switch with an output line of the switch, wherein the particular FA corresponds to the frequency information from the HPB signal; and a Numerical Controlled Oscillator (NCO) connected with the output line of the switch to output the HPB signal to a radio frequency terminal through the particular FA.
