Low-Complexity Joint Source/Channel Turbo Decoding of Arithmetic Codes with Image Transmission Application

摘要

The integration of arithmetic codes (AC) in the most recent coding standards for media applications motivated the development of joint source/channel (JSC) techniques for AC-encoded data. In this paper, we propose a low-complexity scheme which enables iterative decoding for serially concatenated AC and convolutional codes. Iterations are performed between soft input soft output (SISO) component decoders.
