摘要
A method for achieving high bit densities in a direct-sequence spread spectrum communication system by using circular spreading codes. The circular spreading code is a pseudo-noise spreading code that is shifted by n. This circular pseudo-noise spreading code is then used to spread an information signal by modulating the information signal with the circular pseudo-noise spreading code. The same circular pseudo-noise spreading code is also used to demodulate the signal. The value of n used is that which corresponds to the value of the signal to be spread.
