Orthogonal Frequency Division Multiple Access. A technique that allows orthogonal sub-carriers to be assigned to different users.

Orthogonal Frequency Division Multiple Access. A highly flexible multiple-access scheme based on OFDM modem. OFDMA is the predominant multiple-access scheme of choice for beyond 3G (B3G) generation broadband wireless systems such as WiMAX and WiBro. The major benefits of OFDMA include simplicity, high scalability, fine granularity, and capacity-achieving performance. Return

Orthogonal Frequency Division Multiple Access. It's a logical extension of OFDM and a modulation/multiple access technique.
