The key RECENT outcome is a demonstrator providing a comprehensive and mature technology analysis on key schemes addressed. In particular, the key innovations related to WPNC and AMC were simulated and demonstrated within a relevant environment based on real network signals within a HIL (Hardware-in-the-Loop) testbed, illustrating their potential to enhance wireless communication by addressing various QoS guarantees and security concerns.
RECENT outcomes suggests that WPNC and AMC offer substantial advantages, particularly in scenarios with significant Signal-to-Noise Ratio (SNR) headroom. Therefore, these techniques might be useful for small cell deployments or users showing close relay proximity (for e.g. device-to-device communications).
In addition to SNR, various other limitations exist with WPNC that were highlighted in this research. Attempting to undertake network coding while simultaneously addressing Carrier Frequency Offset (CFO) concerns presents a very significant challenges, where no network coding processing may begin before all CFO errors are removed. Achieving production-grade, real-time CFO tracking and compensation, in parallel with channel estimation, is an intricate task that demands dedicated hardware design and HDL implementation that will be addressed as further research.
RECENT simulation results and HIL verification directly boost competitiveness of European industry, both through major companies and their influence in forming future global standards and regulations and for SMEs rapidly exploiting first-hand results, especially in small specialized markets.
This area of study holds immense importance as it is critical to harness the full potential of WPNC in practical, real-world scenarios, providing a step towards secure and reliable communications targeting potential 6G scenarios. The wider societal implications of this work can be far reaching, taking a step towards enabling future emerging B5G/6G scenarios, such as enabling close proximity services (for e.g. V2V for intelligent transportation systems) and delivering lower cost services, whilst having profound economic impact for network operators through traffic offloading and reducing capital expenditure/investments.
