Theoretical Specification of a Spectrum Sensing Receiver for Cognitive Radio
نویسندگان
چکیده
This paper presents the theoretical specification of Spectrum Sensing Receiver used for Cognitive Radios. Its system level design is intended to comply with IEEE 802.22, IEEE 802.16 (Wimax) and LTE standards altogether. The operation frequency band is very wide, from 50MHz to 3.8GHz. Calculated specifications include noise figure, compression point, third order intercept point, sensitivity and signal-to-noise ratio (SNR). Results show the most challenging requirement is the linearity in the entire frequency band. In addition, noise figure become a limitation for detection of weak signals.
