چکیده
---------------------------------------------------------------------***--------------------------------------------------------------------Abstract When unlicensed users need to use the licensed spectrum, it is necessary to detect the unused frequency bands called white spaces. Cognitive radio can be used to do this particular task by dynamic spectrum sensing. This paper explains about detection of unused spectrum for OFDM WLAN (IEEE802.11a) in minimum time by using matched filter based detection and increasing the accuracy in sensing and interference reduction of secondary network.

Matched Filter Based Spectrum Sensing on Cognitive Radio for OFDM WLANs
Abstract For the unlicensed users to use the licensed spectrum, unused frequency bands called white spaces need to be detected. Cognitive radio does this task by dynamic spectrum access. This requires intelligent spectrum sensing techniques. In this paper such unused spectrum for OFDM WLAN (IEEE 802.11a) is predicted by exploring the signals presence in minimum time using matched filter based d...

متن کاملSpectrum sensing and resource allocation for multicarrier cognitive radio systems under interference and power constraints
Multicarrier waveforms have been commonly recognized as strong candidates for cognitive radio. In this paper, we study the dynamics of spectrum sensing and spectrum allocation functions in cognitive radio context using very practical signal models for the primary users (PUs), including the effects of power amplifier nonlinearities. We start by sensing the spectrum with energy detection-based wi...
متن کاملPerformance of OFDM-Based Cognitive Radio
The effect of spectrum sensing errors on the performance of orthogonal frequency division multiplexing based cognitive radio transmission can be evaluated by deriving the expression for the average bit error rate. This depends on various parameters like transmission and spectrum sensing parameters. Here, we consider the case with adding a carrier frequency offset. The spectrum sensing errors of...
متن کاملImproved CR Spectrum Sensing Performance with Lower ACLR GFDM Signals
Generalized Frequency Division Multiplexing (GFDM) with its flexible pulse shaping filters can provide extremely low out of band leakage to adjacent legacy channels. This makes it an attractive choice for a PHY layer of cognitive radios operating in fragmented TV white spaces. Introducing zero padding to the transmission data block significantly reduces the said out of band leakage even further...
