Webb19 jan. 2010 · But Shannon’s proof held out the tantalizing possibility that, since capacity-approaching codes must exist, there might be a more efficient way to find them. The quest for such a code lasted until the 1990s. But that’s only because the best-performing code that we now know of, which was invented at MIT, was ignored for more than 30 years.

Is it applied with passband … This result is known as the Shannon–Hartley theorem. [7] When the SNR is large (SNR ≫ 0 dB), the capacity is logarithmic in power and approximately linear in bandwidth. This is called the bandwidth-limited regime . When the SNR is small (SNR ≪ 0 dB), the capacity is linear in power but insensitive to bandwidth.
