Abstract
An apparatus and method are provided for arranging tones to isolate signals between base stations (BSs) in a high rate packet data (HRPD) system. Packet data is received from a higher layer and the received packet data is channel-coded and modulated. Guard tones are inserted into symbols of the modulated packet data. Pilot tones are inserted using pilot tone arrangements based on preset pilot tone offsets. The packet data symbols to which the pilot tone arrangements have been applied are spread such that BSs for transmitting different broadcast contents are distinguished from each other. A cyclic prefix (CP) is inserted after performing an inverse Fourier transform on the spread packet data symbols, and the symbols are transmitted.
