    Photonic bandgap properties of one-dimensional photonic crystal consisting of complex artificial media

    Propagation of electromagnetic waves in one-dimensional (1-D) stratified chiral structures is described by the 4×4 transfer-matrix method. The photonic bandgap (PBG) properties in 1-D periodical chiral media a...

    New parallel interference cancellation for convolutionally coded CDMA systems

    Based on BCJR algorithm proposed by Bahlet al and linear soft decision feedback, a reduced-complexity parallel interference cancellation (simplified PIC) for convolutionally coded DS CDMA systems is proposed. By ...

    New parallel interference cancellation scheme for DS/CDMA systems

    This paper proposes a new multi-stage parallel interference cancellation scheme by modifying the conventional multi-stage parallel interference canceller (PIC). At each stage, it first converts the interferenc...
