Short Desc. : High Data Rate Demodulator (HDRM-D)
Overview :
The Zaltys High Data Rate Demodulator (HDRM-D) IP core efficiently realizes the digital baseband section of a high performance modem receive path, including quasi-zero IF to baseband conversion, sample decimation, symbol timing recovery, and carrier recovery. Using sophisticated DSP techniques, the core can demodulate BPSK, QPSK, offset-QPSK (OQPSK), 8PSK and 16QAM modulation schemes, all to a high performance level and at high symbol rates.
Features : - Versatile digital demodulation engine for BPSK, QPSK, offset-QPSK (OQPSK), 8PSK & 16QAM
- Close to theoretical performance
- Supports continuously variable symbol rates
- Internal filter decimates up to a factor of 4096
- Supports typical rates of 4.9kbaud to 40Mbaud with 100MHz clock (range scales linearly with clock)
- Four matched filter configurations with alphas of 0.2, 0.25, 0.35 & 0.4 (others available on request)
- Fast acquisition algorithm
- Combined coarse/fine frequency scan
- High probability of first pass acquisition
- Highly configurable and versatile
- Fully programmable via microprocessor interface
- Independent acquisition & track parameters
- Configurable timing & carrier lock characteristics
