Os sistemas de satélites de órbita terrestre não geoestacionários FDMA/TDMA (não GEOS) geralmente requerem um conjunto pré-planejado de recursos de rádio, ou seja, plano de frequência e intervalo de tempo (FTSP), para cada estação terrestre de gateway (GES) antes da real- atribuição de canal de tempo pelos vários GES partilhando os recursos de forma harmoniosa. A natureza variante no tempo desses sistemas implica que um método de planejamento FTSP dinâmico é crucial para a operação lidar com a demanda de tráfego variante no tempo e a condição de interferência entre feixes. Este artigo propõe e compara três algoritmos (algoritmos de numeração serial, baseados em DP e algoritmos Greedy) misturados com duas estratégias (tipos concentrado e espalhado) para a alocação de recursos. A avaliação numérica demonstra que o algoritmo Greedy com estratégia do tipo spread é muito eficaz e promissor com tempo de cálculo viável para a geração de FTSP.

Abstract: FDMA/TDMA non-geostationary earth orbit satellite systems (Non-GEOS) generally require a pre-planned pool of radio resource, i.e., frequency and time slot plan (FTSP), for each gateway earth station (GES) prior to the real-time channel assignment by the multiple GES's sharing the resources harmoniously. The time-variant nature of those systems implies that a dynamic FTSP planning method is crucial to the operation to cope with the time-variant traffic demand and the inter-beam interference condition. This paper proposes and compares three algorithms (Serial-numbering, DP-based, and Greedy algorithms) mixed with two strategies (concentrated- and spread-types) for the resource allocation. The numerical evaluation demonstrates that Greedy algorithm with the spread-type strategy is very effective and promising with feasible calculation time for the FTSP generation.
