Cooperative Spectrum Sensing by Sequential Change Detection in Cognitive Radio
This paper proposes the solution for Spectrum Sensing Problems in Cognitive Radio Networks. For this an Adaptive CUSUM based Test for signal Change Detection algorithm is used. The algorithm is based on sequential change detection techniques which is particularly effective when the parameters are not available apriori or when the correct parameter configuration and the pdf of the signal under t...
متن کاملCooperative Spectrum Sensing Performance-overhead Tradeoff in Cognitive Radio Network under Bandwidth Constraint
In cognitive radio network unlicensed users continuously scan a vast range of frequencies to detect ‘white spaces’ or ‘spectrum holes’ that are temporarily and spatially not being used for communications by licensed user and this process is known as spectrum sensing. In order to execute the cooperative spectrum sensing among cognitive radio users, data fusion schemes are superior to that of dec...
متن کاملAttack-Aware Cooperative Spectrum Sensing in Cognitive Radio Networks under Byzantine Attack
Cooperative Spectrum Sensing (CSS) is an effective approach to overcome the impact of multi-path fading and shadowing issues. The reliability of CSS can be severely degraded under Byzantine attack, which may be caused by either malfunctioning sensing terminals or malicious nodes. Almost, the previous studies have not analyzed and considered the attack in their models. The present study introduc...
متن کاملA Cooperative Uplink Transmission Technique With Improved Diversity-Multiplexing Tradeoff
In this paper a new Decode-and-Forward (DF) cooperative scheme is presented for half duplex uplink transmission. The technique is based on a virtual MIMO structure formed by the single antenna source and relays nodes along with a multiantenna destination node. The new technique aims at providing increased diversity and multiplexing gains, contrariwise to existing approaches in which increased d...
متن کاملThe Diversity-Multiplexing Tradeoff of Delay-Constrained Sequential Streaming
We study sequential encoding of a stream of messages over a block-fading MIMO channel. A new message arrives in each coherence block and the decoder is required to output each message after a delay of T coherence blocks. We establish the optimal DMT and show that it can be achieved using an interleaved coding scheme. The converse is based on a new outage amplification technique. We also discuss...
