WebbThe Shannon–Hartley theorem states the channel capacity , meaning the theoretical tightest upper bound on the information rate of data that can be communicated at an arbitrarily low error rate using an average received signal power through an analog communication channel subject to additive white Gaussian noise (AWGN) of power : where WebbInformation theory is the mathematical study of the quantification, storage, and communication of information. [1] The field was originally established by the works of Harry Nyquist and Ralph Hartley, in the 1920s, and Claude Shannon in the 1940s.

Webbdistortion–free), and the second, which is related, is that the encryption and the decryption units share identical copies of the same key. Yamamoto [11] has relaxed the first assump-tion and extended the theory of Shannon secrecy systems into a rate–distortion scenario, allowing lossy reconstruction at the legtimate receiver. 1.
