Performance Analysis of iNET Using Forward Error Correction and OFDM

Abstract

This paper shows the improvement in performance for OFDM modulation on aeronautical channels with the addition of convolution coding. OFDM is envisioned for use on the Integrated Network Enhanced Telemetry (INET) on aeronautical channels that experience multipath fading which causes inter-symbol interference (ISI). Forward error correction coding, such as convolution coding (cc), significantly improves the bit error rate (BER) of OFDM with multipath fading. Theoretical and simulated results show a performance increase of up to 10dB with the introduction of coding gain and the cyclic prefix (cp). Such improvements can be applied to reduce errors or increase data rates for INET.
