An apparatus for generating pilot beacon signals for handoff between base stations having a different frequency assignment FA in a code division multiple access CDMA radio communication system includes a PN code generating unit for generating inphase (I)-channel and quadrature (Q)-channel pseudo noise (PN) sequences; a pulse shaping unit for shaping an I-channel and Q-channel PN signal by filtering the I-channel and Q-channel PN sequences; an equalizing unit for equalizing phases of the I-channel PN signal and the Q-channel PN signal and generating an equalized I-channel signal and an equalized Q-channel signal; an interpolation filtering unit for converting frequencies of the equalized I-channel signal with the equalized Q-channel signal to intermediate frequencies (IF) and generating an IF I-channel signal and an IF Q-channel signal; a modulation unit for modulating IF I-channel and Q-channel signals and generating a modulated I-channel signal and a modulated Q-channel signal; a combining unit for combining the modulated Q-channel signal and generating a digital pilot beacon signal; and a D/A conversion unit for converting the digital beacon signal into an analog pilot beacon signal.
