pendent of the bit estimation algorithm. The constant minimum variance method (CMVM) is used to suppress interference , We estimate DS-CDMA channel described by Rayleigh fading using a Kalman filter. A Kalman filter is proposed for the time varying channel estimation. The proposed scheme is constructed without hit estimation, that is, neither training(More)
Multi-coded variable PPM (MC-VPPM) is a modulation technique for visible light communication (VLC), providing high data rate transmission and processing gain improvement at the receiver side. This paper proposes wavelength hopping MC-VPPM supporting multi-user communications in the vehicle-to-infrastructure (V2I) downlink and uplink scenarios of a(More)
