Increasing demand for high data-rate real time services has led to the use of shared channels in the forward link for real-time services in 3G wireless networks, such as HSDPA. Strict and differentiated QoS requirements for real-time services, along with time varying channel capacity impose a great deal of challenge on the MAC-hs scheduler. In this paper,(More)
Already used to establish the copyright of graphics, audio and text, digital watermarking is now becoming important for the protection of geometric data. Watermarking polygonal models in the spectral domain gives protection against a range of attacks. We generalize an existing spectral watermarking scheme and propose a new technique based on this(More)
