Let's shake on it: Extracting secure shared keys from Wi-Fi CSI
Tomer Avrahami, Ofer Amrani, Avishai Wool
A shared secret key is necessary for encrypted communications. Since Wi-Fi relies on OFDM, we suggest a method to generate such a key by utilizing Wi-Fi's channel state information…
Sub-Rate Linear Network Coding
Ben Grinboim, Itay Shrem, Ofer Amrani
Increasing network utilization is often considered as the holy grail of communications. In this article, the concept of sub-rate coding and decoding in the framework of linear netw…
Dynamic Network-Code Design for Satellite Networks
Itay Shrem, Ben Grinboim, OFer Amrani
Internet access from space enjoys renaissance as satellites in Mega-Constellations is no longer fictitious. Network capacity, subject to power and computational complexity constrai…
Graph-based Detection of Multiuser Impulse Radio Systems
Y. Shen Bachar, O. Amrani
Impulse-Radio (IR) is a wideband modulation technique that can support multiple users by employing random Time-Hopping (TH) combined with repeated transmissions. The latter is aime…
Direct-Digital-Drive Microring Modulator
Yossef Ehrlichman, Ofer Amrani, Shlomo Ruschin
The method of Direct Digital Drive is applied to a microring resonator. The microring resonator is thus controlled by a segmented set of electrodes each of which is driven by binar…
