The goal of the hyper-wideband enabled RF messaging (HERMES) project is to investigate advanced micro- systems and techniques for jam-resistant radio frequency (RF) communications. Hyper wideband (HWB) code division multiple access (CDMA) offers many unprecedented benefits for RF communications, including robust resistance to jamming and inference signals, and large coding gain for high data rate communications. Current challenges with implementing such HWB CDMA are the complexity and high power consumption of electrically based systems, particularly the receivers that are suitable for highly secure and robust portable communication appliances for various systems. We propose a novel, highly integrated and energy efficient photonic-assisted HWB receiver with a 10 GHz instantaneous bandwidth, 100kb/s data rate, 40 dB coding gain potentially up to 50 dB) and 70 dB jam-resistance (30 dB of adaptive filtering plus 40 dB of coding gain).
