A rede de TV a cabo (CATV) é uma espinha dorsal ideal para PCS devido à sua natureza predominante e de transmissão. Isto reduz significativamente os custos de implementação e as despesas gerais de transferência. Este artigo propõe duas arquiteturas para o sistema PCS baseado em CATV. Na primeira arquitetura, cada estação base é equipada com múltiplos receptores fixos para fornecer transferências rápidas e contínuas para usuários móveis. No entanto, o custo de hardware para esta implementação é relativamente caro. Para superar isto, na segunda arquitetura, cada estação base é equipada com apenas um receptor sintonizável. Esta arquitetura simples e econômica sofre com a possibilidade de conflito de compensação quando os terminais móveis transferem entre células. Três algoritmos de atribuição de deslocamento baseados nos conceitos de atribuição aleatória, uso de vizinhos e agrupamento, respectivamente, são propostos para resolver o problema de conflito de deslocamento. Os resultados da simulação indicam que aquele com o conceito de agrupamento tem um desempenho muito melhor do que os outros dois esquemas em termos de probabilidade de conflito de compensação.

Abstract: The cable TV (CATV) network is an ideal backbone for PCS due to its prevalent and broadcast nature. This significantly reduces the implementation costs and the handoff overheads. This paper proposes two architectures for the CATV-based PCS system. In the first architecture, each base station is equipped with multiple fixed receivers to provide fast and seamless handoffs for mobile users. Nevertheless, the hardware cost for this implementation is relative expensive. To overcome this, in the second architecture, each base station is equipped with only one tunable receiver. This simple and economic architecture suffers from the possibility of offset conflict when mobile terminals handoff between cells. Three offset assignment algorithms based on the concepts of random assignment, neighbor usage, and clustering, respectively are proposed to solve the offset conflict problem. Simulation results indicate the one with the concept of clustering performs much better than the other two schemes in terms of offset conflict probability.
