BER Performance Analysis of Frequency-Hopping and Direct-Sequencing Spread Spectrum for Cognitive Radio Networks

  title={BER Performance Analysis of Frequency-Hopping and Direct-Sequencing Spread Spectrum for Cognitive Radio Networks},
  author={Simar Preet Singh},
Cognitive radio is an encouraging technology for future wireless communication networks. Due to the rapid increase in wireless services, the RF spectrum is going through a scarcity problem. This has forced mobile operators to participate in multimillion dollar auctions to reserve some spectrum resources. Cognitive radio tries to solve this scarcity problem by effectively using the unused portions of the spectrum. FHSS and DSSS are two spread spectrum technologies used for cognitive radios. In…

Analysis of Spread Spectrum Techniques in Cognitive Radio Networks

Cognitive Radio (CR) is another technology in which a framework can sense its surroundings and adjust to the new working parameters to improve the transmission quality. A flexile and versatile

Proposed Sensing -Transmission Model for Uncoordinated Cognitive Radios

The radio range accessible is a constrained asset and the quantity of devices with high information rates can't be suited in the present static range. The range detecting is the gauge on which the

This paper is an outcome of the doctoral research on Error Control Coding for performance improvement in BER and results of FHSS implementation by Matlab M-file programming and improved BER performance by adaptive coder both have been depicted in the paper.

Energy-efficient cooperative spectrum sensing schemes for cognitive radio networks

This article proposes two energy-efficient and time-saving one-bit cooperative spectrum sensing schemes, which have two stages in the spectrum sensing process, and shows that the sensing time and energy consumption are both reduced significantly in the proposed schemes.

Cognitive radio: making software radios more personal

With RKRL, cognitive radio agents may actively manipulate the protocol stack to adapt known etiquettes to better satisfy the user's needs and transforms radio nodes from blind executors of predefined protocols to radio-domain-aware intelligent agents that search out ways to deliver the services the user wants even if that user does not know how to obtain them.


In this paper, various techniques involved like DS, FH, PN sequences in Spread Spectrum Communication system are discussed using MATLAB.
