O termo poluição piloto nos sistemas IS-95 CDMA é usado para indicar que um grande número de sinais piloto igualmente fortes está presente. Esses pilotos competem entre si para se tornarem servidores e isso causa uma rotação muito alta na liderança dos pilotos na estação móvel. Como consequência, a taxa de sinalização no canal de tráfego aumenta, degradando assim a qualidade da chamada. Apresentamos um método para aliviar o problema da poluição piloto por meio de repetidores. Foram realizados estudos de simulação numa rede CDMA real que sofria de poluição piloto e os resultados foram verificados por ensaios de campo. Eles indicam que os repetidores podem efetivamente melhorar a qualidade da chamada, alterando a distribuição espacial da intensidade do sinal piloto.

Abstract: The term pilot pollution in IS-95 CDMA systems is used to indicate that a large number of equally strong pilot signals is present. Those pilots compete with each other to become the serving one and this causes a very high rotation of pilot leadership at the mobile station. As a consequence, the signaling rate on the traffic channel increases, thus degrading the call quality. We present a method of alleviating the pilot pollution problem by means of repeaters. Simulation studies have been carried out on an actual CDMA network suffering from pilot pollution and the results have been verified by field trials. They indicate that repeaters can effectively improve call quality by altering the spacial distribution of pilot signal strength.
