Symmetric capacity
A binary symmetric channel (or BSCp) is a common communications channel model used in coding theory and information theory. In this model, a transmitter wishes to send a bit (a zero or a one), and the receiver will receive a bit. The bit will be "flipped" with a "crossover probability" of p, and otherwise is received … See more The channel capacity of the binary symmetric channel, in bits, is: $${\displaystyle \ C_{\text{BSC}}=1-\operatorname {H} _{\text{b}}(p),}$$ where $${\displaystyle \operatorname {H} _{\text{b}}(p)}$$ is … See more The binary symmetric channel can model a disk drive used for memory storage: the channel input represents a bit being written to the disk and the output corresponds to the bit later being read. Error could arise from the magnetization flipping, background … See more Shannon's noisy-channel coding theorem gives a result about the rate of information that can be transmitted through a communication channel with arbitrarily low error. We study … See more Very recently, a lot of work has been done and is also being done to design explicit error-correcting codes to achieve the capacities of several standard communication channels. The motivation behind designing such codes is to relate the rate of the code … See more • Z channel See more WebJun 24, 2015 · For a binary symmetric channel, the random bits are given as a) Logic 1 given by probability P and logic 0 by (1-P) ... the channel capacity does not become infinite with infinite bandwidth c) Has a tradeoff between bandwidth and Signal to noise ratio d) Both b) and c) are correct

Capacity sharing softens price competition under either contracting scheme, whereas the optimal capacity-transfer price and equilibrium profits may be nonmonotonically influenced by buyer loyalty.
