Statements. … Webb12 mars 2024 · In other words, there exists some code enabling reliable communication with a rate less than $\frac{1}{2}\log_2(1+{\sf SNR})$, and there is no such code enabling reliable communication with a rate larger than $\frac{1}{2}\log_2(1+{\sf SNR})$. This can be directly verified from Shannon's channel coding theorem with mutual information …

At the time, these concepts were powerful breakthroughs individually, but they were not part of a comprehensive theory. In the 1940s, Claude Shannon developed the concept of channel capacity, based in part on the ideas of Nyquist and Hartley, and then formula… how do you spell carnage
