Orthogonal Frequency-Division Multiple Access (OFDMA)

With Orthogonal Frequency-Division Multiple Access (OFDMA) muliple access is achieved by assigning subsets of sub-carriers to individual users. This allows simultaneous low data rate transmission from several users.OFDMA simultaneously supports multiple users by assigning them specific subchannels for intervals of time.So in short, Each terminal occupies a subset of sub-carriers …
