A CDMA WIRELESS PACKET NETWORK FOR VOICE-DATA TRANSMISSIONS

This letter investigates the possibility of integrating voice and data communications in a CDMA wireless packet network to provide access to a base station over a common short-range radio uplink channel for man y spatially dispersed voice and data user terminals. Speech activity d etection is assumed for voice communications to temporarily devote cod es unused by voice user terminals during silence periods to data trans missions. The network proposed exhibits a good performance both in ter ms of quality of voice communications which is independent of data tra nsmissions and maximum data traffic load supported with bounded delay.
