Modern wireless communication networks need to support a variety of data intensive applications in various medium/channel scenarios. It requires high network throughput as well as robustness against Multiuser Interference (MUI), multipath fading and other channel effects. This is achieved by using the hybrid Direct Sequence Time Hopped CDMA (DS-TH CDMA) systems. In this paper, a novel usage of State-Space...
Impulse noise detection is the key issue, while removing random-valued impulse noise from digital images. In this paper, we present a new impulse detection algorithm based on combination of Luo-statistic and k-means clustering. This paper also presents a novel approach to measure impulse noise density level in the corrupted image, knowledge of which allows us to select suitable parameters for the...
