LEVERAGING PILOT SEQUENCE ORTHOGONALITY FOR LOW COMPLEXITY SPACE-TIME CODING RECEIVERS

This paper explores CPM waveforms used for telemetry purposes, with a specific focus on SOQPSK TG standard and its integration with Space-Time Coding to address the two-antenna problem. Cur rent state-of-the-art receiver algorithms face challenges, including delays, error propagation, and poor performance at low SNR levels. To address these issues, this paper introduces a novel re ceiver design leveraging improved correlation properties of new pilot sequences. The proposed design performs CSI estimation at the pilot detection stage, thus eliminating iterative processes, mitigating long synchronization times, and enhancing receiver performance at lower SNR levels.
