Development Tools
Several software and system simulation tools are available to
assist in developing custom modem architectures based on the
QAM-20 evaluation. These tools include a DSP Library, a
modulator filter design program, a signal simulator design
program, and demodulator design program. All tools operate in
the PC-DOS and the Windows 95 environment.
Filter Design Toolbox (MODFILT)
MODFILT is modulator design tool that performs the following functions:
- Designs the Nyquist filtering coefficients
- User specified ISI symbol length
- User specified excess bandwidth
- Performs interpolation by 4, 8, or 16
- Performs DAC compensation
- Computes spectral performance of filter
- Graphical presentations
- Quantizes coefficients for fixed point HW
- Generates coefficients files for C-language
