Hyper-wideband Enabled RF Messaging (HERMES).
Abstract
The University of California San Diego is researching a new class of spread-spectrum receiver with the ability to operate with very high coding gain. The receiver operates by recovering a signal spread over a minimum frequency range of 10 GHz. In contrast to conventional spread-spectrum receivers, the new device a) eliminates digitization at the full (spreading) rate, b) decodes the channel in a low-latency manner and c) reduces synchronization requirement for the first time. The receiver front-end relies on photonics front-end to perform recovery of the received signal in real time. The new transceiver offers anti-jamming capability not inherent with conventional electronic spread-spectrum receivers. In addition to the high-coding gain objective, the work addresses the feasibility of a monolithically integrated platform that serves as an enabling component for the next-generation signal-processing applications. A specialized control algorithm (operating system) is being investigated in order to transform the new transceiver into a monolithically-enabled, format-independent platform. To develop the new receiver into an operational platform, the work was segmented into a) modeling of silicon/silica physical devices and subsystems; b) operational subsystem testing and signal recovery and c) measuring received signal integrity. Technology limits and comparison with conventional technology is quantified and used to generate performance metrics for the next-generation of spread-spectrum transceivers.
