Abstract
In future 5G networks, end-user demand is expected to surpass network supply, due to the exponentially increasing number of connected devices, in line with the internet of things (IOT) paradigm. Spectrum availability is at a premium due to existing allocations, hence, 5G must make highly efficient use of the remaining spectrum. Spectrally efficient frequency division multiplexing (SEFDM) has the potential to improve spectrum utilisation through bandwidth compression, at the cost of self-induced intercarrier interference. In this work, we demonstrate an interactive real-time SEFDM system for the first time, where users are able to dynamically alter system parameters on demand, and any changes are immediately self-evident visually. Varying SEFDM parameters will impact metrics such as frequency spectrum and different constellation diagrams, the latter illustrating received, equalised and detected SEFDM symbols. Our innovation lies in the development and experimental, real-time implementation of baseband generation, signal assembly, signal decoding and a novel frequency-domain channel estimation and equalisation method for the SEFDM transceiver. Our system compresses the transmitted signal bandwidth up to 60% for BPSK and up to 30% for QPSK, offering significant bandwidth savings, and moving towards satisfying one of the key 5G challenges.
