BPSK with pulse shaping filter

Question asked by Jokind on Jun 9, 2011

Hallo community,

 

I'm looking for a bpsk modulator solution for a university/company project.

 

A fixed 1kHz bitstream should be modulated to a tunable carrier (several 100 kHz to maybe 1 MHz, stepping 10 or 20kHz). A root raised cosine filter for shaping spectrum and for optimizing BER at receiving side is strongly needed.

 

Do you habe an idea for a DDS Chip or upconverter  which fulfills these requirements? Or is a combination of DDS, FIR and DAC or something the better way to realize it? My biggest issue is the high upsampling, I think. Or do you see other difficulties?

 

Thank you in advance,

Jo
