Integrated Voice - Data Transmission in Packet PCN ' s

چکیده
In this paper we present a new multiple access protocol based on DS-CDMA and slotted Aloha random access protocol with reservation for integrated voice and data transmission in packet personal communication networks (PCN). Speech activity detection is assumed for voice terminals who will relinquish their codes during their silence periods to be used by the data terminals. The code will be returned to the voice terminals when they enter a talkspurt. The data terminals contend for the codes using a reservation slotted Aloha protocol. We analyze the performance of the protocol incorporating the multiple access e ects as well as the self interference associated with DS-CDMA systems. Index Terms| DS-CDMA systems, wireless personal communication networks, slotted Aloha, integrated voice-data transmission.

متن کاملPerformance Improvement of Expanded Integrated Local Area Networks (RESEARCH NOTE)
In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...
متن کاملScheduling scheme of packet length-based group-wise transmission for integrated voice/data service in burst-switching DS/CDMA system
This paper proposes a new packet rate scheduling scheme for a non-real time data service over the uplink of a burst switching-based direct sequence code division multiple access (DS/CDMA) system to support the integrated voice/data service. We consider the most general form of optimization problem formulation to determine the optimal number of transmission-time groups along with their data rate...
