Abstract: The standardized SOQPSK-TG waveform integrating Space Time Coding offers a solution to the two-antenna problem prevalent in industrial aeronautical telemetry communications. Existing methods suffer from implementation issues due to iterative process delays as well as error propagation due to joint channel parameter estimation. Moreover, their inefficiency at low Signal to Noise Ratio (SNR) does not allow to fully benefit from soft output demodulator extended performance. Indeed, leveraging insights from Rami Othman’s thesis showcasing a decoder functioning 1.5dB below current thresholds, this paper introduces a scheme tailored for the SOQPSK-TG waveform whose novel techniques overcome these challenges. The proposed algorithms not only enhance synchronization accuracy but also facilitate lower SNR operation, enabling higher bit rate transmissions, better range, and more robust receiver chains in aeronautical telemetry scenarios.
