Abstract :
This paper discloses the basic operation of OFDMA system. Also, it discloses the main features of which is a multi-user access. OFDMA has been compared to other systems, such as CDMA or OFDM system, and this article shows the superiority of OFDMA in connection and in data transmission. In addition, we will also revise up or down connections´ types. For instance, a type of basic model is analyzed comparing to the operating model of OFDMA system. Finally, this paper discloses the operation, advantages, applications and types of pair connection regarding to Orthogonal Frequency Division Multiple Access.
