Matched Filter Based Spectrum Sensing Technique for 4GCellular Network

Abstract

Modern and fast developments of wireless technologies have directed to a great demand for resources. Itcan be seen in the study that the range of existing spectrum is not used effectively, therefore the frequencyband should be observed to ensure proper usage and to have the information of primary or licensed useris very much essential. In this research work uplink of LTE (Long-Term Evolution) is observed throughMF (Matched Filter) spectrum sensing technique of CR (Cognitive Radio) network. This method examinesthe existence of signals in minimum possible time, reduces the hindrances between secondary users,increases accurateness of sensing and provides finest choice of threshold. In Uplink the System modelwhich is used is known as SC-FDMA (Single Carrier Frequency Division Multiple Access). Entiresimulation/results are prepared in MATLAB environment. This study also provides graphical contrastof simulated and theoretical results of matched filter and energy detection technique.
