Abstract
A method for spread-spectrum communication includes forming a complex valued chipping sequence and then using the complex valued chipping sequence to spread or despread data. According to another method, a direct sequence spread spectrum (DSSS) radio performs the steps of receiving a radio-frequency signal and then identifying frequencies within the radio-frequency signal which are associated with noise sources. The DSSS radio then self-adjusts to reduce effects of the noise sources or to reduce interference created by the radio upon other communication channels.
