Abstract orthogonal frequency modulation has successfully solved the Inter Symbol Interference problem in frequency selective wireless environment. An interesting application of …show more content…

In OFDM systems, only a one user can transmit on all of the subcarriers at any given time, and time division multiple access (TDMA) or frequency division multiple access (FDMA) is used to support multiple users. The major disadvantage of this static multiple access scheme is that the fact that the different users perform differently in the same given wireless channel is not being taken in consideration. OFDMA, on the other hand, allows multiple users to transmit simultaneously on the different subcarriers per OFDM symbol at any given time. Since the users perform differently in the channel probability that all users experience the same fade in a particular subcarrier is very low, though it can be assured that the subcarriers are assigned to the users who sees good channel gains on them.
While allowing simultaneous access to multiple users to the medium OFDMA has been shown to reduce multi-path fading, within air interfaces in the IEEE 802.16 standard.
The main advantages of using this multicarrier technology are: higher data rates, longer transmission distance, and better mobility support.
Due to the fact that OFDMA divides the available frequency spectrum into several orthogonal subcarriers, inter-symbol and inter-carrier interference are minimized, or even eradicated. Also, the assignment of these subcarriers to different users for transmission can be done dynamically, both in frequency and time dimension. This flexibility provides a way of boosting
