Abstract
This paper proposed M-ary QAM OFDM system for efficiently transmission in multipath fading environment. And, this system have analyzed reception performance by occurred synchronization error to frequency offset in presence of multipath fading. As a result, it confirmed justification by simulation and BER theory of 64QAM OFDM of SP frame structure for the digital broadcasting.
