Shannon–Hartley theorem - Wikipedia, the free encyclopedia
In information theory, the Shannon–Hartley theorem is an application of the noisy channel coding theorem to the archetypal case of a continuous-time analog communications channel subject to Gaussian...

15.9 ). It makes little or no difference what the correction factor for Q is to obtain a BER above Shannon's Limit. Shannon's Limit is still E/N = 1, or 0 dB SNR. ( Equations 15.1 and 15.9 ). Other relationships are: Pe = erfc [SNR] = erfc [Es/No] These are power ratios.

Approaching the Shannon Limit; The Shannon Limit establishes the maximum capacity of any channel. A channel is subject to bandwidth and noise restrictions, but its capacity can be improved with clever modulation and multiplexing techniques.

(188) Note: Error-correction codes can improve the communications performance relative to uncoded transmission, but no practical error correction coding system exists that can closely approach the theoretical performance limit given by Shannon's law...

The shannon limit of compression can be estimated by extrapolating lower order entropies ... The shannon limit of compression can be calculated by extrapolating datapoints from lower order entropies to infinity. This gives the true entropy and the shannon limit of compression is this true entropy divided by the number of...

The V.34 Modem standard advertises a rate of 33.6 Kbit/s , and V.90 claims a rate of 56 kbit/s, apparently in excess of the Shannon limit (telephone bandwidth is 3.3 kHz). In fact, neither standard actually reaches the Shannon limit.
