A wideband space-time channel model is defined, which captures the multiple dependencies and variability in multicell system-wide operating environments. The model provides a unified treatment of spatial and temporal parameters, giving their statistical description and dependencies across a large geographical area for three outdoor environments pertinent to(More)
Voice over Internet protocol (VoIP) will be commonplace in future wireless standards. Due to the potentially large number of VoIP users in a wireless system, the overhead associated with controlling VoIP transmissions can hinder system performance, unless it is carefully managed. This paper outlines current efforts in B3G (beyond 3G) standards development(More)
— Computer simulations are often used to predict the performance of cellular networks. Typically, link level simulations are used to model the link between the access network (AN) and the access terminal (AT), while system level simulations are used to model a system consisting of many ANs and ATs. Since completely modeling the link between each AN and AT(More)
Revision A of the cdma2000 High Rate Packet Data (HRPD) Air Interface Specification includes a method to serve multiple users in a single packet (3GPP2, 2004), This method is know as medium access control (MAC) layer multiplexing and can facilitate up to 8 users in one packet. It allows Revision A of HRPD to be more effective, when compared to previous(More)
The current definition of the spatial channel model (SCM), presents all the components needed to represent the spatial behavior of the propagation channel for a given mobile. These components are used to generate the complex channel samples that evolve with time, but the position of the mobile remains constant, this is known as quasi motion simulation. As(More)
There is an exceedingly small group of microorganisms that are considered pathogenic in humans relative to the microbial biota—with literally just a few bacterial and viral agents that have the potential to cause disease when transmitted in aerosol form. This group of pathogens has adapted to circumvent the rigors of airborne transport to enter the(More)
