An apparatus and method of compensating for a direct voltage offset in a direct conversion receiver of a wireless communications system is provided. The apparatus includes a voltage control oscillator for generating a local oscillation signal having the same frequency as an input signal, a frequency converter for combining the input signal with the local oscillation signal, a first compensator for determining a first direct voltage offset generated due to a leaked local oscillation signal flowed into the frequency converter, for feeding back a magnitude of the determined first direct voltage offset to the frequency converter and for compensating for the first direct voltage offset, and a first register for storing a magnitude of direct voltage offset for a first variable gain amplifier, wherein the first variable gain amplifier is positioned in a rear end of the frequency converter, connected to the first register, and performs a modem associated offset compensation using a magnitude of direct voltage offset stored in the first register.
