Hi all,
i have been doing my final year project of MIMO-OFDM using gnuradio.
For this i first want to transmit a sine wave and i made a simple
program by the concept used in usrp_siggen.py. Although sine is
recieved successfully and its fft is plotted but it has a very low
amplitude and many harmonics. kindly have a look at my code:
#!/usr/bin/env python
from gnuradio import gr, gru
from gnuradio import usrp
import sys
class my_top_block(gr.top_block):
def __init__(self):
gr.top_block.__init__(self)
#1. source
#2. sink
#3. connect
self.interp = 64
self.sink = usrp.sink_c (0, self.interp) # Transmitter code
self.usb_freq = 1000000
self.src = gr.sig_source_c(self.usb_freq, gr.GR_SIN_WAVE,
2450000000, 32000, 0)
self.src.set_frequency(input('Set the frequency'))
self.connect(self.src, self.sink)
def main():
tb=my_top_block()
#tb.subdev.set_enable(True) # enable transmitter
try:
tb.run()
except KeyboardInterrupt:
pass
if __name__ == '__main__':
main ()
Thanks in advance
Regards,
Ebtisam
