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.
