Abstract

The need for efficient transmission of data is of primary concern with growth in technology. With this increased demand comes a growing need to transmit information wirelessly, quickly and accurately. To address this need, communications engineer have combined technologies suitable for high rate transmission with forward error correction (FEC) techniques. This is particularly important as wireless communications channels are far more hostile as opposed to wire alternatives, and the need for mobility proves especially challenging for reliable communications. Channel coding plays a very important role in OFDM systems performance. The structure of OFDM systems makes channel coding more effective in confronting fading channels. Different types of data such as image transmission require larger bandwidth as well as redundancy from noise. Encryption data from noise is an important aspect and this can be obtained by channel coding. This article provides an overview of OFDM basics and focuses on efficient data transmission over OFDM.
