RF Engines has completed a digital radio receiver architecture study for the French Atomic Energy Commission (CEA) Laboratories.
The system, which has been developed by the Isle of Wight-based firm, is capable of detecting and characterising signals with a broad range of different modulation schemes and durations. This work follows on from an earlier evaluation of RF Engines Pipelined Frequency Transform (PFT) demonstration system by the CEA.
RF Engines has signed a contract to implement a laboratory demonstration system that will incorporate the results. The system is due for delivery in 2006, and will be used by the CEA to investigate complex signals.
“We have been able to demonstrate how RF Engines’ unique signal processing architectures provide solutions to some of the most difficult problems in the design of complex digital receivers,” said John Summers, RF Engines’ CEO.
Whereas many receiver architectures tend to be optimised for receiving one particular signal type, the PFT architecture, patented by RFEL, has a multi-resolution capability, which allows the input spectrum to be processed through a range of different filter bandwidths simultaneously. This means that there is always a filter available that is close to the optimal type required for every signal type, thereby maximising the likelihood of detection and enhancing the quality of the analysis, said the firm.
