Abstract

In coding theory, concatenated codes form a class of error-correcting codes that are derived by combining an inner code with an outer code. This is a solution to the problem of finding a code that has both exponentially decreasing error probability with increasing block length and polynomial-time decoding complexity. The work presented in this paper, provides link level performance analysis of non-line of sight (NLOS) QPSK-OFDM data transmission over Rayleigh fading channels. Two scenarios have been considered in this paper. Firstly, the performance of un-coded and coded 1024-pointOFDM over the AWGN channel was obtained. Secondly, using Jake's sum of sinusoids model, the link level performance of the system was obtained over the COST 207 Rayleigh fading channels (Typical Urban and Bad Urban) and the Winner vehicular NLOS (RS-MS-NLOS) channel. To the best of the authors' knowledge, this work is first in presenting the individual/compared contributions of CC, RS and RS-CC coded version of QPSK-OFDM over the COST 207 TU/BU channels.
