Overview
The COM-1519SOFT is a digital direct-sequence spread-spectrum modulator written in VHDL, including modulation, multiple baseband interfaces, DAC drivers, and ancillary test features. It is designed to be embodied within a single low-cost FPGA
- Direct-Sequence Spread-Spectrum (DSSS) modulation
- BPSK, QPSK
- Codes: Gold, Maximal length, Barker, GPS C/A
- Spreading factor: 3 to 65535
- Continuous mode operation (i.e. Burst mode is not supported)
- Modulation: BPSK, QPSK
- Maximum chip rate = fclk/2
- Baseband interfaces:
- Synchronous serial interface with Plesiosynchronous buffer or
- TCP-IP interface
- USB 2.0 interface
- Ancillary components:
- Test signal generation
- Channel impairements (additive white Gaussian noise, Doppler)
- Drivers for three types of high-speed digital-to-analog converters.
