Read online. Compression of remote sensing images is beneficial to both storage and transmission. For lossless compression, the upper and lower limits of compression ratio are defined by Shannon's source coding theorem with Shannon entropy as the metric, which measures the statistical information of a dataset. Webb5 dec. 2024 · The key contribution that Shannon made was to show that if random coding is used at the transmitter and typical set decoding is used at the receiver then transmission at a rate I ( X; Y) − ϵ can be achieved whilst also upper bounding the maximum bit error rate to ϵ.

"WebbOne major diﬀerence between Shannon’s noiseless coding theorem and in-equality (2.3) is that the former applies to all uniquely decipherable codes, instantaneous or not, whereas the latter applies only to instantaneous codes. Next, we extend the source coding theorems given by Parkash and Kakkar [12] in the context of channel equivocation. " - Shannon's source coding theorem
