A transmission technology in which a data signal at the sending station is combined with a higher data rate bit sequence, or chipping code, that divides the user data according to a spreading ratio. The chipping code is a redundant bit pattern for each bit that is transmitted. If one or more bits in the pattern are damaged during transmission, the original data can be recovered due to the redundancy of the transmission. Also see frequency hopping spread spectrum.
