Cascaded Neural Networks For Sequenced Propagation Estimation, Multiuser Detection, And Adaptive Radio Resource Control Of Third-Generation Wireless Networks For Multimedia Services, William S. Hortos

Electrical Engineering and Computer Science Faculty Publications

A hybrid neural network approach is presented to estimate radio propagation characteristics and multiuser interference and to evaluate their combined impact on throughput, latency and information loss in third-generation (3G) wireless networks. The latter three performance parameters influence the quality of service (QoS) for multimedia services under consideration for 3G networks. These networks, based on a hierarchical architecture of overlaying macrocells on top of micro- and picoells, are planned to operate in mobile urban and indoor environments with service demands emanating from circuit-switched, packetswitched and satellite-based traffic sources. Candidate radio interfaces for these networks employ a form of wideband CDMA …
