Abstract
A new method for achieving spectrum reuse in cellular systems, called capture-division packetized access (CDPA), has been introduced by Borgonovo, Fratta and Zorzi (see Proc. of ICCC Wireless Computer Networks '94, The Hague, Netherlands, Sept. 1994). The method is based on packet switching and uses a single frequency in all cells. Mobiles belonging to the same cell transmit packets using C-PRMA, a polling-like mechanism. Simultaneous transmissions in different cells are made possible by the "capture" capability. Packets that are not captured are almost immediately retransmitted, thus assuring that they are eventually correctly received. Previous analytical works show that CDPA throughput presents a potential gain over classical schemes as FDMA with a 7 cell reuse pattern. We present a simulation model of a cellular system which uses the CDPA technique to accommodate the traffic generated by continuous traffic sources, uniformly scattered over the cellular area. The results encourage one to go ahead in the investigation of the viability of the CDPA approach.Keywords
