Spectrum Sensing Detection with Sequential Forward Search in Comparison to Known Signal Information

FCC is currently working on the concept of white space users “borrowing” spectrum from free license holders temporarily to improve the spectrum utilization. This project provides a relation between a Pf and the SNR value of any spectrum detector to have a certain performance. Previous spectrum sensing detection techniques are only suitable for Low SNR and are based on signal information values. But these methods are purely narrow band spectrum applications In order to overcome the above said drawbacks we propose a novel method of spectrum sensing method and is suitable for low and high SNR values, the sensed spectrum applicable for wide band applications. Our proposed method does not require signal information at the receiver and channel information, because this flexibility sensing rate is very high compared to previous techniques.
