1. Channel capacity

   Channel capacity, in electrical engineering, computer science, and information theory, is the tight upper bound on the rate at which information can be reliably transmitted over a communication channel. Following the terms of the noisy-channel coding theorem, the channel capacity of a given channel is the highest information rate (in units of information per unit time) that can be achieved with arbitrarily small error probability. Information theory, developed by Claude E. Shannon in 1948, defines the notion of channel capacity and provides a mathematical model by which it may be computed. The key result states that the capacity of the channel, as defined above, is given by the maximum of the mutual information between the input and output of the channel, where the maximization is with respect to the input distribution. The notion of channel capacity has been central to the development of modern wireline and wireless communication systems, with the advent of novel error correction coding mechanisms that have resulted in achieving performance very close to the limits promised by channel capacity.

1. channel capacity

   Channel capacity, in information theory, refers to the maximum rate at which information can be reliably transmitted over a communication channel. This is often measured in bits per second. The channel's capacity depends on the channel's bandwidth, noise level, and error rate. Channel capacity represents the highest possible average information transmission rate that does not result in error, given certain constraints such as signal power and noise.

1. Channel capacity

   In electrical engineering, computer science and information theory, channel capacity is the tightest upper bound on the rate of information that can be reliably transmitted over a communications channel. By the noisy-channel coding theorem, the channel capacity of a given channel is the limiting information rate that can be achieved with arbitrarily small error probability. Information theory, developed by Claude E. Shannon during World War II, defines the notion of channel capacity and provides a mathematical model by which one can compute it. The key result states that the capacity of the channel, as defined above, is given by the maximum of the mutual information between the input and output of the channel, where the maximization is with respect to the input distribution.

Examples of channel capacity in a Sentence

1. Brett Whitin:

   We’re up approximately 7.5 million acre feet in California storage since last year at this time, so already a significant gain in water supply and this snowpack is going to benefit those reservoirs, as opposed to melt in the spring, but it will be a challenge to manage all this snowpack. I mean, there’s been record snow and a lot of these rivers have limited channel capacity downstream, so getting that water out safely is going to be a challenge.
