  OFDM (Orthogonal Frequency Division Multiplexing)provides the promising
physical layer for 4G and 3GPP LTE Systems in terms of efficient use of
bandwidth and data rates. This paper highlights the implementation of OFDM in
Digital Video Broadcasting-Terrestrial (DVB-T). It mainly focuses on the timing
offset problem present in OFDM systems and its proposed solution using Cyclic
Prefix (CP) as a modified SC (Schmidl and COX) algorithm. It also highlights
the timing synchronization as well as performance comparison through bit error
rate. Synchronization issues in OFDM are important and can lead to information
loss if not properly addressed. Simulations were performed to implement DVB-T
system and to compare different synchronization methods under certain
distribution model.
