OFDMA – Orthogonal Frequency Division Multiple Access
OFDMA (Orthogonal Frequency Division Multiple Access) can be described as an extreme application of channelization. However, whereas OFDM sub-channelization is semi-static, OFDMA permits a more dynamic allocation of resources. Thus, OFDMA will allocate a number of sub-carriers for different symbol periods based upon network conditions and user’s requirements. This enables better utilization of the available bandwidth by minimizing waste.
