In the market of wireless local area network (WLAN), high data-rate transmission has been the trend. IEEE 802.11g standard works at 2.4GHz ISM band and supports data rates up to 54Mbits/s using OFDM modulation. To achieve the desired performance upper bound, it is crucial to deliver a close match of I and Q signals in both the modulator and the demodulator.
