Demodulators
Shaped Offset Quadrature Phase Shift Keying - Telemetry Group (SOQPSK-TG) is a type of QPSK/OQPSK modulation. SOQPSK-TG provides constant-envelope modulation with continuous phase. This minimizes spectral occupancy and improves resistance to interference and nonlinear amplification.
The SOQPSK-TG Demodulator IP Core is a complete coherent demodulator that features fully digital symbol and carrier synchronization, a high dynamic range of gain control, and a soft-decision LLR output.
Key Features:
- Compliant with the Telemetry IRIG 106-22 Standard
- Supports SOQPSK-TG, SOQPSK-MIL, SOQPSK-A and SOQPSK-B
- Coherent demodulation
- Digital dynamic range of 40 dB
- Symbol rates from Fclk/4 to Fclk/65536
- Low implementation loss
- LLR soft decision for LDPC and Turbo FEC
- Easy integration with JESD204B ADC
