Abstract :
A novel up-link one-shot code acquisition procedure is proposed based on a structured preamble sequence. The general strategy is applied to the context of third generation satellite networks. A multi-dwell approach is introduced to simplify the detection of a long preamble. The parallel detection of the two basic sequences forming the preamble is coordinated by a novel HLC (high level controller). Passive and active differential post detection integrations are selected to perform detection during the search and verification phases, respectively. Performance is evaluated and optimized with respect to the most significant system parameters.
