Abstract
An orthogonal code hopping multiple access communication system divides channels according to hopping patterns of the orthogonal codes allotted to the respective channels. The communication system includes a transmitter for modulating input digital signals using an orthogonal code hopping multiple access technique and transmitting the modulated digital signals, and a receiver for receiving the digital signals using the orthogonal code hopping multiple access technique and restoring the digital signals.
