ALS162 Time Signal SDR Receiver for GNU Radio
A real-time SDR receiver of the French time signal ALS162 is studied, implemented and tested for GNU Radio. Inspired by the practical observations and the minor but yet appealing challenges encountered, this receiver provides another supportive learning exercise for practical signal processing with GNU Radio. Along with the transmitter and receiver design, the present paper addresses several commonly used signal processing concepts like signal synthesis, FIR and IIR filters, phase modulation, phase drift compensation, basic synchronization, symbol correlation, decision metrics and error detection that are applied in terms of GNU Radio
