2. Bit-Rate Allocation, Scheduling, and Statistical Multiplexing for Wireless Video Streaming
Abstract : Due to the scarcity of wireless resources, efficient resource allocation is essential to the success of cellular systems. With the proliferation of bandwidth-hungry multimedia applications with diverse traffic characteristics and quality of service requirements, the resource management is becoming particularly challenging.

3. Downlink Resource Allocation in Cooperative Wireless Networks
Abstract : Wireless cooperative networks, which is based on exploiting coordination among multiple access nodes, has been considered as a promising approach to improve the spectral efficiency, reduce the energy consumption, and extend the network coverage of future wireless communication systems. In practice, the actual benefit of multi-node cooperation is affected by a variety of factors, including the quality of channel state information (CSI), the constraints on the feedback and backhaul links, hardware impairments, resource allocation and data processing schemes.

4. Cost efficency of nonresponse rate reduction efforts : an evaluation approach
Abstract : Nonresponse, the failure to obtain complete measurement on all sample elements, is an increasing problem in sample surveys. Efforts to reduce the nonresponse rate are expensive and their effect may not be as desired. READ MORE

5. Resource Allocation in Downlink Coordinated Multi-Point Systems
Abstract : The raised user expectations of quality of service and the rapid growth of the data traffics impose a great challenge for mobile communication systems. The performance, e.g., the spectrum efficiency, peak data rate, cell-edge data rate, of current cellular systems ismainly limited due to the presence of inter-cell interference. READ MORE
