High Data Rate Enhanced Demodulator
- Versatile digital demodulation engine supporting BPSK, QPSK, offset-QPSK (OQPSK), 8PSK, 8QAM* (three variants), 16QAM, 32/64QAM (HDRM-D2 core only) & 16/32APSK (HDRM-D2 core only)
- Close to theoretical performance
- Option to increase datapath resolution to help cope with elevated levels of adjacent carrier interference (HDRM-D2 core only)
- N-stage symbol rate blind adaptive equaliser option reduces linear channel distortions such as multipath (HDRM-D2 core only)
