Here is a list of all our events, come find us!
ReachRF will be presenting a recently accepted paper to SAE WCX 2018 entitled: “Best Practices in OBU Antenna Procurement for Connected Vehicle Deployments”. As V2X deployments take off, we explore the best practices from real-world CV deployments focused on the most important component of CV deployments, the antenna.
ReachRF will be speaking to ITS industry professionals in the State of Georgia at the ITS GA February chapter meeting in Atlanta, GA. Hosted by Temple, Inc, we will be speaking about the 5-Star Automotive Cyber Safety Program, helping ITS firms focus on design by security first.
ReachRF will be representing for I Am The Cavalry at the 5G for Automotive event in Colonge, Germany. Hosted by IQPC, we will be speaking about the V2X deployments here in the United States and addressing the 5-Star Automotive Cyber Safety Program, helping connected car firms understand the need for design by security first, rather than security after design. Look for us and come by and chat about CV tech.
Going back to Singapore almost a year later, this time to give a talk about new machine learning models developed by ReachRF for the latest Doppler sensor: ADS. See you at the 2017 IEEE Global Communications Conference: Ad Hoc and Sensor Networks
Cepstral Analysis for Classifying Car Collisions in LOS/NLOS Vehicle-to-Vehicle Networks
In this work the Doppler effect is exploited for identifying a collision between two vehicles under Line-of-Sight (LOS) and Non-Line-of-Sight (NLOS) conditions. A measurement campaign at 5.9GHz is conducted to observe the Doppler effect for Vehicle-to-Vehicle (V2V) networks. In our previous work, we developed a collision avoidance estimator based on tracking the LOS Doppler shift in the Doppler domain. We now report real-world captures of the Doppler phenomenon in terrestrial V2V networks during a collision and present a method for collision identification by tracking the NLOS Doppler spread in the channel. Through machine learning, classification of collision feature observations is accurate with an accuracy of nearly 100% and reliable with a misclassification rate less than 1%.
We;re headed to beautiful Orlando, FL to give a talk about a channel model we adapted for rapid prototyping of the Doppler profile in simulation. Come hear us at the 14th International Conference on Mobile Ad-hoc and Sensor Systems (IEEE MASS 2017)
Vehicle-to-Vehicle LOS Large-Scale Doppler Channel Model using GSCM
The Doppler effect is typically an impairment for wireless communications in mobile-to-mobile environments. Multipath effects leading to delay dispersion at the receiver can create to a challenging doubly selective time-frequency channel response. In Vehicle-to-Vehicle (V2V) communications small-scale effects of the V2V channel over a short duration are well understood. However, observing the Doppler response over a longer duration can provide observations directly related to the vehicle dynamics. In this novel work, we build upon an existing GSCM by including the double-bounced scattering off of the participating vehicles themselves and validating these contributions through real-world experimentation. The model enables the study of a potentially new “sensor” in connected vehicle networks: the large-scale Doppler response, in which mobile scatters are observable and potentially communication environment awareness.
ReachRF will be in attendance at the Florida Autonomous Vehicle Summit 2017 showing off a new sensor for AVs. Stop by our poster and get ready to be amazed by our new RF sensor.
We are presenting a paper at the ITS World Congress 2017 in Montreal, Canada. Stop by our talk, and be sure to network with us in the exhibit hall! See you there. Special thanks to ITS GA for their support of our student research efforts.
Tracking RSSI in Vehicle-to-Vehicle Networks for Collision Avoidance
The RSSI is readily provided by V2V radios. In this paper, we explore how a V2V radio could predict vehicular collisions by observing the RSSI over the duration of a V2V link between two cars. Trends indicative of a collision are noticeable, but the dealing with false alarm rates can be tricky.
Nippon! The land of the rising sun and signal processing. Come hear about ReachRF and some exciting discoveries about the DSRC channel. We will be presenting our research at the 18th IEEE International Workshop on Signal Processing Advances for Wireless Communications.
Automotive Doppler Sensing: The Doppler Profile with Machine Learning in Vehicle-to-Vehicle Networks for Road Safety
In this work, we present the fundamentals of a new sensing technique in Vehicle-to-Vehicle networks (V2V) called: Automotive Doppler Sensing (ADS), for providing road safety to connected drivers and connected autonomous vehicles by observing the Doppler profile. ADS is a powerful new 360 degree “sensor” to provide both context awareness of the driving scenario and collision avoidance services, even in NLOS conditions.
See you at ICC 2017!
We’ll be presenting a paper entitled:
Frequency Injection Interfacing: A Novel Method for Delivering External Information to an OFDM Receiver Physical Layer
This work presents a novel method we call: Frequency Injection Interfacing (FII), for OFDM communication systems. With FII, an external system or observer can communicate to an OFDM receiver through a frequency encoder that injects additional frequency content into the received signal. FII could potentially allow new applications and optimizations for OFDM systems, without requiring a separate application program interface. A packet reception rate above 95% proves FII operates transparently within existing OFDM architectures, furthermore the non-optimized implementation of FII presented in this work reveals that FII could reliably deliver up to 2047 code words with 67% success and zero false alarms.
ReachRF will be giving a talk at the Atlanta, GA Meetup group: Sensors and Startups to talk every V2V in the United States. Come on out and hear more.
Abstract: Have you heard? Last month, the U.S. Department of Transportation’s National Highway Traffic Safety Administration has issued another Notice of Proposed Rulemaking (NPRM) to mandate vehicle-to-vehicle (V2V) communication technology for new light vehicles in the United States. This makes V2V set to hit the world stage to help reduce car accidents, but relying on message passing for accident prevention may not be the most reliable way to protect drivers. In this talk, we give a background on V2V communications, discuss the political-industry-academia status of the technology, and some novel methods for predicting collisions in V2V networks currently being developed at the Georgia Institute of Technology.
