Universal Software Radio Peripheral (USRP) [8] or Realtek-
Software Defined Radio (RTL-SDR) can be used. USRP is
a transceiver developed by Ettus Research and National Instruments.
It turns a host computer into a wireless prototyping
system. While USRP however is costly, RTL-SDR is a low cost
alternative. RTL-SDR is a cost effective software defined radio
that uses a DVB-T TV tuner dongle based on the RTL2832U
chipset. It is also often referred to as RTL2832U, DVB-T SDR,
RTL dongle or the $20 Software Defined Radio.
