FBMC/OQAM-related new waveform
Résumé
This exhibition proposes to demonstrate a new waveform based on filter bank multicarrier (FBMC) modulation as one of the promising technology components enabling efficient air-interface for several new usage scenarios. This is done through a complete hardware implementation on an FPGA-based digital baseband (DBB) platform of both techniques with similar architectural choices. Novel hardware optimisations are proposed to reduce implementation complexity. Target key-performance indicators (KPIs) include spectrum usage, hardware complexity, latency, and energy efficiency. Being a physical-layer component, it constitutes an enabler to many usage scenarios as it enhances system robustness in several impairment cases: (1) against narrowband interference encountered in an ultra-dense network (UDN) where cellular and device-to-device (D2D) users coexist and perfect synchronization may not be easily ensured and (2) against high Doppler shifts encountered in mobile environments.
