MY GNURADIO CODE:
from gnuradio import gr, uhd
import numpy
samplerate=4*106
symbolrate=106
sampersym=samplerate/symbolrate
tx=gr.top_block()
snk0=uhd.usrp_sink(‘serial=1R24XAU1’,uhd.io_type.COMPLEX_FLOAT32,1)
snk0.set_samp_rate(samplerate)
snk0.set_center_freq(2.44*10**9)
src0= gr.file_source(gr.sizeof_gr_complex,‘msgtxd.dat’,False)
tapval=gr.firdes_root_raised_cosine(sampersym,
samplerate,symbolrate,
0.35,sampersym*11)
fil = gr.interp_fir_filter_ccf(int(sampersym),
tapval)
tx.connect(src0,fil,snk0)
tx.run()
print ‘done’
Please help.
