Abstract
To meet the ever growing demand of data rates, many modern wireless systems have adopted multicarrier modulation schemes. Nowadays, Orthogonal Frequency-Division Multiplexing (OFDM) is the most commonly used multicarrier modulation scheme that offers efficient use of bandwidth. To tackle intersymbol interference and avoid complex channel equalization, OFDM is usually used in combination with a Cyclic Prefix (CP). However, CP-OFDM comes with its own limitations such as the need of precise time and frequency synchronization, high out-of-band radiation as well high peak-to-average power ratio. Therefore, researchers have started investigating alternative multicarrier modulation schemes. Among others, Filter Bank Multicarrier (FBMC) is gaining a lot of attention due to its optimized prototype filters that eliminate the need of CP and reduce out-of-band radiation and, hence, offers further improvement in bandwidth utilization. In this work, we develop a Software Defined Radio (SDR) based FBMC testbed that operates in real time. We use GNU Radio as a software part of SDR in combination with Universal Software Radio Peripherals (USRPs) for over-the-air experiments. In contrast to state of the art, our FBMC transceiver exploits frequency domain synchronization and can easily be tuned for various bandwidths. By conducting over-the-air measurements, we show that the developed testbed can successfully be used even in presence of other narrowband systems in the same frequency bands. For the purpose of reproducibility, we make the testbed implementation also publicly available.
