802.11a uses Orthogonal Frequency Division Multiplexing (OFDM) to help solve the multipath distortion problem. OFDM divides the data into multiple subcarriers that are transmitted simultaneously, each with slightly different frequencies. This enables the receiver to accurately reconstruct the original signal, even if some of the subcarriers are attenuated or delayed due to multipath distortion.
