Raised Cosine Filter design

Hi,
I want a raised cosine filter for the transmitter and can someone lead
me to
a place where I can develop one similar to what we have in gr_firdes.h

Thanks

Look at the source code used to generate the raised cosine, gr_firdes.h
should point to it. Making your own should follow directly from that;
also
the wikipedia page on the raised cosine is also nice.

Its not black magic, so do not fear the source. :stuck_out_tongue:

Yep! Done. fred harris’ book helped the most.

Thanks

That is the best source currently in my opinion especially his
discussion of
HOW BAD RAISED COSINE FILTERS ARE AS NYQUIST FILTERS FOR DATA
TRANSMISSION.
