Channel use[1] is a quantity used in signal processing or telecommunication related to symbol rate and channel capacity. Capacity is measured in bits per input symbol into the channel (bits per channel use). If a symbol enters the channel every Ts seconds (for every symbol period a symbol is transmitted) the channel capacity in bits per second is C/Ts. The phrase "1 bit per channel use" denotes the transmission of 1 symbol (of duration Ts) containing 1 data bit.
