Webb23 apr. 2008 · Shannon’s noisy channel coding theorem is a generic framework that can be applied to specific scenarios of communication. For example, communication through a band-limited channel in presence of noise is a basic scenario one wishes to study. The 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 … Visa mer In information theory, the Shannon–Hartley theorem tells the maximum rate at which information can be transmitted over a communications channel of a specified bandwidth in the presence of noise. It is an application of the Visa mer 1. At a SNR of 0 dB (Signal power = Noise power) the Capacity in bits/s is equal to the bandwidth in hertz. 2.
