Abstract

Though OFDM has many advantages like Spectral efficiency, robust to multipath fading, it is highly sensitive to synchronization error caused by Carrier Frequency Offset (CFO), and Sampling Clock Offset (SCO). These offset reduces the orthogonality in OFDM which degrades the system performance. For to improve the efficiency of the system Inter Symbol Pilot Aided Synchronization Algorithm is introduced in this paper for estimating the offset. The data is transmitted in Asynchronous Mode of Transmission since it has better than synchronous mode of transmission.
