In this paper, the performance of one of the most widely deployed Wireless Local Area Networks (WLANs) based on IEEE 802. 11a standard has been analyzed using different modulation technique and convolution coding rates. The IEEE 802. 11a standard uses Orthogonal Frequency Division Multiplexing (OFDM) technique. In this paper, the channel estimation is pilot symbol based. A particular method proposed in literature, known as the Least Square method (LS), along with its enhancement using Discrete Fourier Transform (DFT) based estimator is investigated in this paper.
