碩士 === 國立臺灣科技大學 === 電機工程系 === 105 === Orthogonal Frequency Division multiplexing(OFDM) system is widely used in the 4th generation of mobile phone mobile communication technology standards (4G). However, the system exists inter-carrier interference (ICI) which caused by the high spectral sidelobe level of each subcarrier in channel or interface. Filter-bank multi-carrier (FBMC) system has been proposed to overcome this problem, but it also turns out that the huge complexity and long symbol duration become the drawbacks of FBMC. Universal-filtered Multi-carrier (UFMC) system that was proposed to combine the advantages of two system uses a filtering operation which applies to a resource block (RB) to suppress the sidelobe of OFDM and reduce the complexity of FBMC. Also, UFMC is a candidate waveform for the next generation of wireless communication. Carrier Aggregation (CA) is one of the most important technique in LTE-Advanced. By aggregating carrier components (CC) in different spectral, the system can highly increase the data rate. Therefore, in this paper, we propose a system called Carrier Aggregation in Universal-filtered Multi-carrier (CA-UFMC) system to improve the data rate in UFMC system. Moreover, we analyze the bit-error rate in the system. UFMC system can also apply the detection scheme in OFDM, so we compare them in the proposed system. Further, we use different filter types to the system to achieve high quality of signal.
