Spectrum Allocation And Scheduling In Cognitive Radio For 4G Lte Networks

Cognitive radio is a low-cost communication system, which can choose the available frequencies and waveforms automatically on the premise of avoiding interference of the licensed users. The spectrum sensing is the key enabling technology in cognitive radio networks. It is able to fill voids in the wireless spectrum and can dramatically increase spectral efficiency. In this thesis, we used matlab to simulate the received signals from the cognitive radionetworks and an energy detector to detect whether the spectrum is being used. The report also compares the theoretical value and the simulated result and then describes the relationship between the signal to noise ratio (SNR) and the detections. At last, the method, energy detection with Matched Filter detection simulation and result are discussed which is considered as the guidelines for the future work. LTE, an initials’ of Long Term Evolution, marketed as 4G LTE, is a standard for wireless communication of high-speed data for mobile phones and data terminals. It is based on the GSM/EDGE and UMTS/HSPA network technologies, increasing the capacity and speed using a different radio interface together with corenetwork improvements. The standard is developed by the 3GPP (3rd Generation Partnership Project) and is specified in its Release 8 document series, with minor enhancements described in Release 9.That is why I have chosen 4G LTE Network for Spectrum Allocation. It will be more advanced and beneficial for all wireless mobile communication
