Development and performance evaluation of filterbank multicarrier systems

Abstract

As an alternative to OFDM systems with Cyclic Prefix (CP), filter bank multicarrier (FBMC) transmission technique leads to an enhanced physical layer conventional communication network and it is an enabling technology for the new concepts and, particularly, cognitive radio. Due to the feature of good time-frequency localization, there is no need for FBMC systems adding any guard interval, definitely leading to higher spectral efficiency compared with CP-OFDM. FBMC has the potential to fulfill the requirements of the new concepts, but a major research effort is necessary for full exploitation and optimization in all aspects of the radio context. In this paper, a testbench based on National Instrument universal software radio peripheral has been developed for FBMC systems. Meanwhile, systematic performances, including synchronization, channel estimation and bit error rate are evaluated.
