Sub-Band Filter in Universal Filtered Multi-Carrier Transceiver for Cognitive Radio Network

摘要

Modern wireless mobile communication system concentrates on effective utilization of frequency band and efficient modulation technique for side lobe elimination. Frequency bands are effectively utilized by using Cognitive radio networks. Cognitive radio network (CRN) is one of the intelligent technologies to solve spectrum scarcity. Universal Filtered Multi-Carrier (UFMC) is the potential multi-carrier modulation technique for the fifth generation (5G) wireless communication networks, as it detains the side lobes of spectral component and also reduces the effect of inter-carrier interference. In this paper, we design the UFMC transceiver whose parameters are adjusted in response to the challenge of side lobe removal. To this end, we first estimate the Peak-to-Average power Ratio (PAR), optimum sub-band filter length at the transmission and the bit error rate (BER) at the reception. The proposed UFMC transceiver can be applicable for the detection of unused spectrum by exploiting the autocorrelation properties of received signal. Finally we verify the performance of proposed UFMC transceiver for the application of CRN by computer simulation.
