General information
- Short Summary
- An Italian High-tech SME designing electronic systems and technologies for communications has developed a novel RF modulation (UDWM waveform) that exhibits excellent robustness to Doppler and Doppler rate RF signal impairments and makes the modulation perfectly suited for communications that involve vehicles or objects moving at very high speed like satellites, drones, rockets, or airplanes. Industrial partners from aeronautics and space sectors are sought for technical and commercial agreements
- Full Description
-
UDWM waveform aims to open up new development opportunities for low-power and low-cost Aerospace and SATCOM systems, and it is especially applicable to LEO, small satellite networks (i.e. CubeSat), IoT, and aeronaval applications.
One core technology that enables reliable and efficient communication links is signal modulation. Single-carrier (ASK, PSK, FSK, QAM) and multi-carrier (OFDM) are the most commonly used in satellite and aerospace environments.
Other solutions have been proposed with the increasing development of the satellite and aerospace industries. In particular, one emerging and very interesting modulation technique is the Chirp Spread Spectrum (CSS) which has been assessed and tested in the last couple of years.
That modulation is mainly used in ground IoT networks (e.g. LoRa) because of its long-range capability and low implementation cost.
The authors of this waveform patented a novel CSS modulation technique, named UDWM (Up/Down-chirp Width Modulation), intending to implement it and make it available for a broad range of communication applications.
UDWM was modeled using a mathematical simulator and the results of the simulations bring out several features that a communication system can exploit.
A list of the main UDWM advantages follows:
1. high Doppler/Doppler rate immunity (it is suitable for LEO and very high-speed peer applications),
2. very low sensitivity (that leads to small antenna size requirement),
3. constant envelope (that leads to maximum power amplifier efficiency and low power consumption),
4. very low modulation/demodulation complexity (no FPGA is required - low-cost implementation),
5. better canalization compared to GMSK and other modulations (simpler RF front-end).
The Italian High-tech enterprise based in Padua and working in the field of Electronic Design is now looking for industrial partners from aeronautics and space sectors to further develop the technology from the TRL 2 current state to all the possible market applications. - Advantages and Innovations
-
LEO constellations realize global coverage and the link distance is shorter compared to the other types of satellites, which means that the size and power consumption of the system equipment (payload, terminals, etc.) can be small.
On the other hand, LEO SATCOM receivers face high Doppler and Doppler rate effects because of the satellite speed.
Similar issues are faced by drones, rockets, and other flying objects.
Chirp Spread Spectrum (CSS) based modulations offer good Doppler immunity and UDWM is even better with its unique property of coding the symbols as full range chirp sequences on a constant time period.
That feature makes it immune to the Doppler rate too and increases the link reliability. In addition, UDWM has the same sensitivity performance and power efficiency (it is a constant envelope modulation) compared to the best-in-class LoRa benchmark.
That permits minimizing the antenna size and the required transmission power.
Lastly, the symbol coding and decoding implementation are simpler with respect to other CSS modulation types, which means the TX/RX frontends can be smaller and consume less power. - Stage of Development
