Performance of XFAST in the presence of code Doppler by TANG Xiao-mei, YONG Shao-wei, WANG Fei-xue

“…The probability of detection and false alarm in XFAST（extended replica folding acquisition search technique） were introduced in the condition of code Doppler and deterioration of noise caused by replica folding.The simulation re-sults show that the model is correct,the equal signal to noise error is less than 0.5dB.The research is the academic base of XFAST parameter optimization and performance.When the extended replica folding number equal to 1,the model can be used to analyse other acquisition algorithm.…”

Improved cooperative spectrum sensing scheme based on dempster-shafer theory in cognitive radio network by Mei-ting YU, Lin-jing ZHAO, Zhao LI

“…An improved cooperative spectrum sensing scheme based on dempster-shafer evidence theory in cognitive radio networks was proposed.In the local sensing period,the projection approximation algorithm was introduced to reduce bandwidth for cooperation.In the fusion period,credibility was calculated by the distance between evidence vectors of different secondary users and adopted as the weights to combine different local sensing data.The new scheme reduces channel bandwidth and simulation results show that the new scheme improves the performance under the condition of high level conflict.…”
