Preliminary BER Study of a TC - OFDM system operating under noisy conditions

Wireless systems contain transmitters and receivers in order to exchange information. In the past decades, this exchange of information was conducted with the use of only one modulated carrier (frequency). As wireless technology evolved, new techniques emerged. One of them was unique for its capability of significant lower data loss compared to others. The main concept of the new technique, commonly known as Orthogonal Frequency Division Multiplexing, was the utilization of various orthogonal carriers (frequencies), which were multiplexed with each other in order to prevent system breakdown in the case of frequency fading. In this paper we simulated our enhanced OFDM platform based on Turbo Coding (TC) in the presence of a noisy channel (AWGN, Phase noise, Rician noise, ITU PA3) exhibiting excellent BER performance.
