Performance investigation of a sparse data compression technique with AWGN channel effects

摘要

The paper introduces a performance measure for data sources that may be used to evaluate the potential for good compression using a sparse source coding technique, as well as BER bounds in AWGN. The authors present comparative results of sparse source coding and, in terms of the introduced performance measure, complexity and error propagation in AWGN conditions. Simulation results show that the performance measure can be used effectively to predict the potential of a source for compression. Comparative PDF and BER results are shown for various sparseness levels in coded and uncoded systems.
