FPGA Implementation of a DSSS Digital Receiver
()
Abstract:
The Direct Sequence Spread Spectrum (DSSS)technology has been used widely in both military and civil communication.A flexible DSSS digital receiver based FPGA is introduced. Some key technologies, such as the model of DSSS digital receiver, the PN code detection, the PN code tracking, are analyzed.Finally, the measurement results are also shown.
Key words:  Direct sequence spread spectrum(DSSS),Digital receiver,PN code detection,PN code tracking,Software radio,FPGA
