install gnuRadio Linux [source]

langsung aja ya yg ga tau gnuradio bisa searching :P
nah kali ini ketemu untuk menginstallasi gnuradio pada pc server atau pc sendiri
gnuradio di gunakan untuk menangkap signyal gsm yang di bantu dengan alat usrp *CMIIW

library tambahan

Update

sudo apt-get update

Instal untuk Maverick (11.4) 

sudo apt-get -y install libfontconfig1-dev libxrender-dev libpulse-dev swig g++ automake libtool python-dev libfftw3-dev libcppunit-dev libboost-all-dev libusb-dev fort77 sdcc sdcc-libraries libsdl1.2-dev python-wxgtk2.8 subversion git-core guile-1.8-dev libqt4-dev python-numpy ccache python-opengl libgsl0-dev python-cheetah python-lxml doxygen qt4-dev-tools libqwt5-qt4-dev libqwtplot3d-qt4-dev pyqt4-dev-tools libpcre3 libpcre3-dbg libpcre3-dev libpcrecpp0

sebaiknya sebelum menginstall gnuradio usrp sudah terhubung ke portusb nya

download openbts source di sini

Install gnuRadio

cp gnuradio-3.3.0.tar.gz /usr/local/src/

cd /usr/local/src/

tar zxvf gnuradio-3.3.0.tar.gz

cd /usr/local/src/gnuradio-3.3.0/

./configure

make clean

make all

make

make check

make install

sudo ldconfig

Jika saat menjalankan aplikasi gnuradio ada error seperti

ImportError: libgnuradio-core-3.3.0.so.0: cannot open shared object file: No such file or directory

Lakukan / ketik

sudo ldconfig

verifikasi gnuradio

Selanjutnya kita perlu memverifikasi apakah GNURadio dapat bekerja dengan USRP. Untuk tahapan ini kita perlu menyambungkan USRP ke komputer.

Cek kecepatan sambungan USB ke USRP

cd /usr/local/src/gnuradio-3.3.0/gnuradio-examples/python/usrp

./usrp_benchmark_usb.py

Akan keluar sbb:

Testing 2MB/sec... usb_throughput = 2M

ntotal    = 1000000

nright    = 999918

runlength = 999918

delta     = 82

OK

ntotal    = 2000000

nright    = 1999492

runlength = 1999492

runlength = 7997680

delta     = 2320

OK

Testing 32MB/sec... usb_throughput = 32M

ntotal    = 16000000

nright    = 15995986

runlength = 15995986

delta     = 4014

OK

Max USB/USRP throughput = 32MB/sec

 

Error libgnuradio-core

Jika ada error

ImportError: libgnuradio-core-3.3.0.so.0: cannot open shared object file: No such file or directory

lakukan

sudo ldconfig

Cek C++ Interface ke USRP
