From last few decades, wireless communications industry is gaining momentum in both fixed and mobile applications. The continued increase in demand for all types of wireless services (voice, data, and multimedia) is fuelling the need for higher capacity and data rates not only in fixed but also in mobile applications. There are many techniques that fulfill these requirements. One of the most important techniques is Orthogonal Frequency Division Multiplexing (OFDM). In this paper, the authors analysis the performance of wireless OFDM system using rapter codes. The time-varying features of wireless communication channels adversely affect the performance of the system.
