发帖数: 2 | 1 In OFDM transmitter, the modulated symbols need to be pulse shaped before
transmitting. I built a filter in Matlab2013a using
d = fdesign.pulseshaping(16,'Raised Cosine', 'Ast,Beta', 60, 0.3);
H = design(d);
fvtool(H);
In previous Matlab version, a function can be used both for filter design
and apply to IFFTed symbol data:
rcosflt(subcarriers, 1, 20, 'fir',0.4,10)
However in 2013a version, I couldn't find information to apply this filter
to IFFTed symbol data. Does anybody know how to do it?
Thank you! |
