Joint source-channel decoding scheme for image transmission over wireless channel

A Joint Power Allocation and Adaptive Channel Coding Scheme for Image Transmission over Wireless Channels

“…In some systems, like second generation GSM mobile radio systems, channel coding is used selectively for message bits that carry more information while no coding is used for less important bits [6]. A variation of the channel coding approach is joint source/channel coding (JSCC) [7], [8], [9], [10], [11], [12], [13], [14], [15]. In contrast to Shannon's information separation theorem [16], schemes employing JSCC jointly tradeoff source and channel coding to achieve significant performance improvements over separate source and channel coding.…”
