MOXZ - Modulation On X Zeros
In cooperation with the California Institute of Technology, the Technical University of Berlin, and the California University of Irvine, we invented a new blind modulation scheme for wireless communication. MOXZ is a fundamentally new, digital modulation approach for the physical layer that can handle the most challenging scenarios. Key features are:
- Large Bandwidths - Multipath Diversity.
- Low Latency - Ultra short signals.
- Low Power - Blind signaling, no training required.
- High Mobility - Doppler Robustness.
- Precise Positioning - Radar properties.
We are a team of highly-skilled, RF researchers and engineers at the Technical University Berlin in the Institute of Telecommunications seeking partners and investors to spin-off our new technology, MOXZ.
From Blind Communication to the Internet of Things
By predicting a huge paradigm shift in early 2010 within wireless communication — driven by a machine-type communication in automation and industrialization — we worked on a radical new concept for modulating digital data on the physical layer. Between 2017 and 2019 we developed a novel blind (noncoherent) communication scheme, called modulation on conjugate-reciprocal zeros (MOCZ), to reliably transmit sporadic short binary packets over unknown finite impulse response systems. Which can be used, for example, to model underspread wireless multipath channels. The MOXZ Principle is to encode the information in the location of the zeros of the transmitted signals z-transform. In the absence of additive noise, the zero structure of the signal is perfectly preserved at the receiver, regardless of the channel impulse response (CIR) realization. With a proper selection of the zero locations, we showed that MOCZ is not only invariant to the CIR, but also robust against additive noise. Furthermore, from a simple zero testing algorithm we engineered an extremely reliable and low-complexity decoder which enables low-power and low-latency.
Joint Sensing and Communication
MOXZ signals allow due to their Radar properties communication and sensing at the same time, which enable new use-cases such as
