“…Classical information theory shows that separate
source-channel coding is asymptotically optimal over a
point-to-
point channel.As modern communication systems are becoming more sensitive to delays and bandwidth,it becomes difficult to adopt the assumption that such separate designs have unlimited computing power for encoding and decoding.Compared to joint
source-channel coding,separate
coding has proven to be sub-optimal when the bandwidth is limited.However,conventional joint
source-channel coding schemes require complicated design.In contrast,data-driven deep learning brings new designing ideas into the paradigm.A summary of relevant research results was provided,which will help to clarify the way in which deep learning methods solve the joint
source-channel coding problem and to provide an overviewof new research directions.Source compression schemes and end-to-end communication system models were firstly introduced,both based on deep learning,then two kinds of joint
coding designs under different types of source,and potential problems of joint
source-channel coding based on deep learning and possible future research directions were introduced.…”
