Overview
- Direct-Sequence Spread-Spectrum (DSSS) demodulation of intermediate frequency (real) input or baseband (complex) input signals.
- Continuous mode operation (i.e. Burst mode is not supported).
- Maximum processing gain: 33 dB. Spreading factor: 3 to 2047.
- Code period can be (significantly) longer than symbol period:
Maximal code period: 65535 - Maximum chip rate: 50% of processing clock frequency.
- 78 Mchips/s Xilinx Spartan-6 -2
- 99 Mchips/s Xilinx Kintex-7 -2
- Parallel code search for fast code acquisition. The number of parallel search circuits instantiated within can be selected by the user prior to synthesis.
- False code lock prevention.
- Accurate time of arrival pulse generated once per code period (can be used for round-trip delay measurement for example).
- Built-in Bit Error Rate measurement.
- VHDL source code included.
