Description

Physical Optics Corporation (POC) proposes to advance our new Scalable Parallelized LInk data Transmission Through Embedded Referencing (SPLITTER) device that was architected, designed, prototyped and proved feasible through system analysis and prototype testing. SPLITTER is a self-contained programmable digital data stream disassembler and reassembler that successfully overcomes bandwidth fragmentation problems in SATCOM. It does so by splitting data streams into substreams and assigning these to unused spectral energy segments (bandwidth fragments). SPLITTER sits between the data source and transmitter and is completely communication transparent allowing it to work on C, X, Ku, KA, and Q bands and is not effected by angular polarization variations, frequency, data path length, or energy per bit. The Phase I prototype demonstrated overhead 250 ms, and guarantees accurate data stream reassembly in non-symmetrical and agile data streams. The design does not employ duplication, and the embedded self-referencing linking methodology eliminates the need for reference channels. In Phase II, we will develop an advanced prototype by porting our computationally simple software to FPGA-based hardware that supports data rates from 1bps to 10Gbps. We will develop a hardware testbed to support test and evaluation at Aberdeen proving grounds Joint Satellite Engineering Center (JSEC).
