Approximate performance analysis and simulation study forvariable-channel-per-burst SS-TDMA

An analysis is presented of the traffic performance of a variable-channel-per-burst (VCPB) satellite-switched time-division multiple access (SS-TDMA) that dynamically reconfigures traffic bursts. An SS-TDMA system with an onboard baseband switch is used as the VCPB application system. Bursts are assigned to each earth station one-by-one. Idle channels of other bursts are transferred to a burst having an insufficient number of idle channels by reconfiguration on a call-by-call basis. The VCPB is suited to SS-TDMA systems with relatively few earth stations. VCPB traffic performance depends on the reconfiguration strategy. The effects on traffic performance caused by reallotting idle channels to all bursts in every reconfiguration are described. An approximate formula for the reconfiguration probability from the loss probability of fixed-channel-per-burst TDMA weighted by the binomial distribution for the number of channels in each burst is derived
