Báo cáo hóa học: " Research Article Error Recovery Properties and Soft Decoding of Quasi-Arithmetic Codes" pdf

... paper addresses the problem of optimal and reduced complexity soft- input decoding of QA codes with a termina- tion constraint. An optimal state model for soft- decoding of QA codes, exploiting a ... to analyze error recovery properties of VLC is extended to QA codes. This method allows the calculation of the PMF of the gain/loss of symbols caused by channel errors...
