In this paper the authors focus on the implementation of transreciever for the IEEE 802.11a WLAN standard which incorporates OFDM as its multiplexing and modulation technique. An OFDM is a multi-carrier modulation technique which divides the available spectrum into many subcarriers. Due to the orthogonality of carriers and sharing of data, OFDM has high bandwidth efficiency. The OFDM can be viewed as many slowly modulating narrow signals instead of a single rapidly modulating wide-band signal.
