Abstract

For real world communication systems that operate in correlated fading channels, perfect channel state information is not always available. In the literature, performance curves for error correction codes are usually plotted from either closed form equations or simulations which assume perfect channel state information. While these methods of measuring the capabilities of error correcting codes do serve a theoretical purpose, they do not necessarily demonstrate how well a code will perform under non-ideal conditions. The goal of this paper will be to compare LDPC and Turbo codes and determine how well they perform when perfect channel state information is not available at the receiver. Bit error rate and some block error rate performances will be provided for the AWGN, Rayleigh and 1Hz 1ms multipath fading channel. The results of this paper may provide communication systems designers some useful insight into the actual performance of error correcting codes in real-world scenarios.
