  A telecommunication system uses carriers in order to transmit information
through a cable or wirelessly. If each time only one carrier is transmitted,
then the system s signal will not be immune to frequency selective fading. If
frequency selective fading includes the working frequency of the system, then
the wireless link will not be established. Orthogonal frequency division
multiplexing OFDM is the primary solution for coping with inter signal
interference and frequency selective fading. Many carriers can be produced by
splitting a fast information stream to slower data series. Different orthogonal
frequencies carry slower data series. System s performance can be further
enhanced with the utilization of turbo codes. Turbo codes make the system more
immune to noise effects with excellent BER results. This paper presents the
thorough analysis of a turbo coded OFDM scheme using a PCCC technique in the
presence of a channel which includes AWGN, phase noise, Rayleigh fading, Rician
fading and Doppler shift.
