Weyl Spreading Sequence Optimizing CDMA
نویسندگان
چکیده
Recently, the new spreading sequence obtained by the Weyl sequence is proposed for CDMA systems. Its crosscorrelation function follows O( 1 N ), where N is the code length of the spreading sequence. In this paper, we optimize the Weyl sequence code design to assign to each user for CDMA systems and we analytically calculate its theoretical SIR (Signal to Interference Noise Ratio). It is theoretically proven that the CDMA systems with spreading sequence has about 2.5 times larger capacity of users than the CDMA systems with the Gold code.

متن کاملNonlinear Multiuser Receiver for Optimized Chaos-Based DS-CDMA Systems
Chaos based communications have drawn increasing attention over the past years. Chaotic signals are derived from non-linear dynamic systems. They are aperiodic, broadband and deterministic signals that appear random in the time domain. Because of these properties, chaotic signals have been proposed to generate spreading sequences for wide-band secure communication recently. Like conventional DS...

متن کاملA Novel Multi-user Detection Approach on Fluctuations of Autocorrelation Estimators in Non-Cooperative Communication
Recently, blind multi-user detection has become an important topic in code division multiple access (CDMA) systems. Direct-Sequence Spread Spectrum (DSSS) signals are well-known due to their low probability of detection, and secure communication. In this article, the problem of blind multi-user detection is studied in variable processing gain direct-sequence code division multiple access (VPG D...
