– We present a multiple-channel video transmission scheme in wireless CDMA networks over multipath fading channels. We map an embedded video bitstream, which is encoded into multiple independently decodable layers by 3D-ESCOT video coding technique, to multiple CDMA channels. Each video source layer is protected by a product channel code structure. For a(More)
—This paper proposes an optimization scheme on uplink pilots time interval (UPTI) in terms of maximum average post–processing SNR (signal to noise ratio) for a time division duplex (TDD) multiple input single output (MISO) beamforming system with channel estimation error and delay. In TDD system, the base station estimates the channel state information(More)
In this study, stroke patients received constraint-induced movement therapy for 3 weeks. Before and after constraint-induced movement therapy, the flexibility of their upper limbs on the affected side was assessed using the Wolf motor function test, and daily use of their affected limbs was assessed using the movement activities log, and cerebral functional(More)
