Abstract

This paper proposes a half-chip offset QPSK (Quadrature Phase Shift Keying) modulation CDMA (Code Division Multiple Access) scheme to allow the simple differential detection while realizing a compact spectrum in nonlinear channels for wireless LAN (Local Area Network) systems. The experimental results show the proposed scheme combined with Forward Error Correction (FEC) achieves excellent Pe performances in adjacent channel interference (ACI) and co-channel interference (CCI) environments and significantly improves the frequency utilization efficiency.
