引用
"Small satellites are widely used today as cost-effective means to perform Earth observation and other tasks that generate large amounts of high-dimensional data."
"JSCC-SAT provides better quality than source coding using JPEG 2000 combined with channel coding using LDPC for most parameter combinations."
