This letter proposes a novel deregistration strategy-group deregistration-for PCS networks. In the proposed strategy, instead of deregistering a mobil...

Grouping voice frames from multiple calls into a single packet as a means to reduce bandwidth requirement for IP voice calls is investigated. It is de...

We derive a layered space-time scheme for multi-antenna orthogonal frequency-division multiplexed transmissions over frequency-selective channels. Com...

The capacity and the interference statistics of the sectors of the shaped W-CDMA cell are studied. A model of five cells is used to analyze the uplink...

This letter presents a new construction of frequecny-hopping (FH) codes for the multilevel frequency-shift-keying/frequency-hopping code-division mult...
