| description | In this paper we present the experimental
implementation of dynamic spectrum access (DSA) algorithm
using universal software radio peripheral (USRP) and GNU
Radio. The setup contains two primary users and two cognitive
radios or secondary users. One primary user is fixed and the
other is allowed to change its position randomly. Depending upon
the position of the primary user the cognitive user will use the
spectrum band where the detected energy is below certain
predefined threshold level. The cognitive radio users are also
programmed to operate independently without interfering with
each other using energy detection algorithm for spectrum
sensing. The modulation scheme is set to GMSK for secondary
user performing data transmission. This experimental setup is
used to analyze the quality of video transmission using DSA
which provides the insight regarding the possibility of using free
spectrum space to improve the performance of the system and its
advantage over a non-DSA system. From the experiment it is
shown that under congestion and interference DSA perform
better than a non- DSA system. |
