This technique also provides a PN code , designed to demodulate QPSK or BPSK data from a carrier whose frequency is 11 MHz or less. Data rates can be as high as 1Mbit/s for QPSK signals or 500Kbit/s for BPSK signals. An error signal is produced, which can be used to acquire and track the PN code of a direct sequence spread spectrum system. This ... Original

consisting of a pseudo-random noise (PN) sequence. PN sequences, however, are not random; they are synchronized replica of the original PN code. On the down link in a CDMA base station (base station to mobile station), the information to each user is encoded with a different digital coding signal (PN sequence). Because the PN sequences are orthogonal to one another, they exhibit minimum cross correlator along with other interfering signals. When a correlator PN sequence matches the PN
