Matlab-based simulator of cooperative spectrum sensing in real channel conditions

Abstract

This paper presents the developed MATLABbased simulation environment used to evaluate the cooperative spectrum sensing in the simulated channel conditions. Four different channel models can be set up between the primary user and individual secondary users: PedA, PedB, VehA and VehB models. Two types of detectors -the energy detector and the Kolmogorov-Smirnov-based statistical detector have been implemented and then used for the evaluation on the two types of transmitted signals -the analogue FM signal and the digital 8PSK signal. The simulator has also been used in order to demonstrate the effectiveness of the cooperative approach over the spectrum sensing via the single devices.

Expansion of Cluster Head Stability Using Fuzzy in Cognitive Radio CR-VANET

“…Kasem et al presented a MATLAB based simulator of cooperative spectrum sensing with different channel atmosphere. The created model performance was tested in Vehicular and Pedestrian channel with different communication signal and four cooperative users [21].…”

A Novel Fair and Efficient Resource Allocation Scheduling Algorithm for Uplink in LTE-A

“…The 3GPP proposes the Typical Urban channel model (TU) to represent densely populated areas with highest path loss. The Rural Area (RA) channel model is suggested for less populated areas [16]. The Pedestrian channel model (Ped) is for mobile users with low-mobility, with speed less than 30 km/h.…”
