We report on a novel implementation of a photonics-based RF interference mitigation system which is capable of suppressing same-frequency interference from a known signal at least 40 dB stronger than the signal-of-interest. Our technique will be valuable in future simultaneous transmit and receive (STAR) systems.
Distributed source coding techniques enable distributed receivers to independently compress samples to a rate above the Slepian-Wolf bound, by leveraging statistical correlations between different receivers observations. The wireless channel can impose many compression challenges, such as unknown or dynamic compression bounds due to time-varying fading and mobility. This work derives a novel rate...
Distributed arrays provide a way to exploit MIMO and other array transmission and processing approaches using several single-antenna nodes connected via an Intra-Cluster Network (ICN). Recruitment of nodes within the transmit cluster for relaying a distributed space-time block code (STBC) transmission can be coordinated by a source node. Subject to synchronization and coherence recovery, when the...
In this paper we investigate practical adaptivity methods for tactical multiple-input multiple-output (MIMO) applications that need to operate on-the-move in variable multipath environments. The key features of these methods include the ability to estimate in real-time the MIMO channel between the transmitter and receiver in a dynamic multipath environment, select the highest performance spatial operating...
