The Hybrid State-space Navigation Paradigm: Eliminating Digital Signal Processing in Band-limited Wireless Channels
Year: 2026
Type: preprint
Abstract: This paper introduces AxisAura Radio, a foundational wireless communication architecture that overthrows the contemporary high-frequency gigahertz race (3.5 GHz–60 GHz) by shifting the physical-layer mechanism from waveform-dependent modulation to passive state-space navigation within the sub-gigahertz (<1 GHz) spectrum. Modern wireless standards (5G NR, Wi-Fi 6E/7) maximize spectral efficiency through dense Quadrature Amplitude Modulation (up to 4096-QAM) coupled with Orthogonal Frequency-Division Multiplexing (OFDM). However, this introduces an exponential computational overhead, requiring billions of multiply-accumulate operations per second executed by active, power-hungry Digital Signal Processing (DSP) units to mitigate phase noise, multipath fading, and Doppler shifts. AxisAura Radio completely bypasses the real-time waveform reconstruction pipeline. By utilizing a formalized multi-dimensional state-space mapping, data segments are treated as discrete coordinate vectors mapped bijectively into a sub-GHz spectral grid. Validated performance metrics under a 868 MHz ISM carrier frequency demonstrate a scalable goodput of 300–500 Mbit/s within a compact 2.56 MHz bandwidth (256 discrete 10 kHz slots). This architecture achieves a 30–50x reduction in energy-per-bit expenditure (<1 nJ/bit), provides robust immunity to multipath interference and Doppler distortion, and extends the non-line-of-sight (NLOS) urban propagation radius by an order of magnitude compared to traditional 5 GHz coherent systems. AxisAura Radio establishes a new layer of abstraction for long-range, ultra-low-power, high-throughput wireless networks and next-generation IoT infrastructures.
