Abstract
A method of transmitting and receiving a spread spectrum signal, wherein a product of a lower bit rate signal and a second PN-code equals the bit rate of a higher bit rate signal, and wherein a first PN-code sequence is used to spread the product or the higher bit rate signal to a predetermined output chip rate signal which is transmitted. At a receiver, the spread spectrum signal is received and demodulated and in a first operation the demodulated signal is correlated with the first PN-code sequence and in a second operation the output from the first mentioned correlating step is correlated with the second PN-code sequence. The demodulated signal is treated as either a higher bit rate signal or a lower bit rate signal based on the first and second correlations operations.
