modulation technique for wireless communications. OFDM can provide large data

rates with sufficient robustness to radio channel impairments. Many research centers

in the world have specialized teams working in the optimization of OFDM for

countless applications. Here, at the Georgia Institute of Technology, one of such

teams is in Dr. M. A. Ingram’s Smart Antenna Research Laboratory (SARL), a part

of the Georgia Center for Advanced Telecommunications Technology (GCATT).

The purpose of this report is to provide Matlab　code to simulate the basic processing

involved in the generation and reception of an OFDM signal in a physical

channel and to provide a descr iption of each of the steps involved. For this purpose,

we shall use, as an example, one of the proposed OFDM signals of the Digital

Video Broadcasting (DVB) standard for the European terrestrial digital television

(DTV) service.
