Blind Estimation of Frame Synchronization Patterns in Telemetry Signal

Abstract

Telemetry signals are widely used in order to control electric equipment, collect information for launching satellites and for testing aircraft and guided weapons. In non-cooperative contexts, a blind estimation algorithm is essential to acquire data from telemetry signals. Generally, telemetry signals have a frame structure which consists of data words and a unique frame synchronization pattern. To obtain the telemetry signals blindly, we have to estimate the synchronization patterns in the frame structure first. In this paper, we propose a new algorithm for the estimation of frame synchronization patterns for the blind detection of telemetry signals and verify the proposed algorithm through computer simulations. By exploiting this algorithm, structures of unknown telemetry signals can be reconstructed.
