Source model aided lossless turbo source coding

The integration of a source model into lossless source coding based on punctured turbo codes is considered. We use the turbo principle to iteratively estimate the source statistics and to compensate the errors due to compression. In order to cope with the critical part of joint estimation and decoding, the start-up, we propose the use of an asymmetric turbo code with one recursive Quick-Look-In component code. Moreover, we present an alternative puncturing method, which ensures the compression of the data in a predetermined number of reconstruction attempts. Simulation results show that the proposed scheme outperforms traditional source codes when compressing data with memory.
