Shannon's capacity formula
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. Visa mer 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. Visa mer The basic mathematical model for a communication system is the following: where: • $${\displaystyle W}$$ is the message to be transmitted; • $${\displaystyle X}$$ is the channel input symbol ( Visa mer The noisy-channel coding theorem states that for any error probability ε > 0 and for any transmission rate R less than the channel capacity C, there is an encoding and decoding … Visa mer • Bandwidth (computing) • Bandwidth (signal processing) • Bit rate • Code rate Visa mer If G is an undirected graph, it can be used to define a communications channel in which the symbols are the graph vertices, and two codewords may be confused with each other if their symbols in each position are equal or adjacent. The computational … Visa mer An application of the channel capacity concept to an additive white Gaussian noise (AWGN) channel with B Hz bandwidth and Visa mer This section focuses on the single-antenna, point-to-point scenario.
