Cognitive Radio System Supremacy Channel Configuration

Abstract

Utilization of unused spectrum in wireless communications is a revolutionary advancement known as cognitive radio that is initially allocated only to licensed services. Here, we propose a design for control channel in this network (cognitive radio network). Multi carrier spread spectrum is employed as a control channel in cognitive radio system. Among the types of control channel underlay/Overlay control channel is preferred.  FBMC subcarrier is localized. Also, we propose a Blind channel estimation technique for control channel. Comparison between OFDM and FBMC based MC-SS is analyzed and suggested that FBMC is better. SNR and BER in MC-SS are calculated.
