| Abstract(in English) | This paper focuses on a novel multicarrier modulation scheme called Filter Bank Multicarrier (FBMC). It has drawn significant attention in the cognitive radio (CR) community due to its extremely low Adjacent Channel Leakage Ratio (ACLR). Besides the advantageous spectral properties of FBMC, it also has some drawbacks which are to be resolved: the large Peak-to-Average Power Ratio (PAPR) of the transmitted signal makes it especially vulnerable against nonlinearities present in the transceiver chain; multipath channels with large delay spreads induce significant amount of inter-symbol interference (ISI), calling for complex channel equalization for acceptable Bit Error Rate (BER) performance. In this paper, these two problems are investigated and solutions are suggested. First, Orthogonal Frequency Division Multiplexing (OFDM) based PAPR reduction possibilities suitable for FBMC are introduced, then channel equalization schemes are discussed which enable efficient channel equalization with reduced BER compared to conventional techniques. |
