Abstract:
Abstract— JPEG is a widely deployed image compression standard used in several applications. However, JPEG image transmission is challenging and sophisticated strategies are required for reliable transmission. This paper investigates the performance of JPEG image transmission using duo-binary Turbo codes with Unequal Error Protection (UEP). UEP is achieved by applying a lower code-rate to protect the DC-layer of the image more efficiently and a higher code-rate for protecting the AC-layer. Additionally, the duo-binary Turbo code is enhanced by scaling its extrinsic information to improve performance and by using a stopping criterion to limit the number of iterations required for decoding. The proposed UEP scheme provides a gain of at least 10 dB in Peak Signal to Noise Ratio (PSNR) over an Equal Error Protection (EEP) scheme for a range of Eb/No values. Moreover, the gain in PSNR increases as the couple length of the duo-binary code is increased.
