Abstract: Joint source and channel coding (JSCC) has been attention to information theory and transmission systems recent two decades. Recently one new joint source and channel coding based on Double LDPC codes, particularly based on Protogragh Double LDPC Codes (JSCC with PD LDPC Codes) has been investigated according to its lower power and low complexity characteristics. In this talk how to improve the waterfall and error floor of bit error rate (BER) performance of JSCC with PD LDPC Codes is discussed first through adaptive rate allocation between source and channel coding. Secondly proposed system with unequal error protection scheme is investigated through imaging transmission. It is found that above proposed systems own great advantages on imaging transmission with lower power and complexity relative to traditional JSCC. Finally it is found that source statistics affects more obviously the proposed system performance than multi antenna, which provides one new direction how to optimize the system performance.
