TECHNIQUES AND DESIGN FOR WIDE-BAND CORRELATION OF DIGITAL OR ANALOG DATA STREAMS

A NEW TECHNIQUE FOR PERFORMING REAL-TIME WIDE-BAND CORRELATION IS PROPOSED. THE TECHNIQUE IS BASED ON THE USE OF HIGH SPEED ANALOG OPTICAL TECHNOLOGY TO PERFORM HIGH SPEED AND RELATIVELY LOW TIMEBANDWIDTH PRODUCT ANALOG CONVOLUTION OR CORRELATION, TOGETHER WITH OPTICAL INTERCONNECT DEVICES TO PERFORM APPROPRIATE DATA ROUTING AND PERMUTATION OPERATIONS. ADDITIONALLY, THIS CONCEPT INCLUDES THE USE OF MODERN, HIGHLY-PARALLEL, NUMER-THEORETIC CONCEPTS BASED ON LARGESCALE FFT ALGORITHMS TO DECOMPOSE THE LARGE SCALE-WIDE-BAND CORRELATION INTO A SET OF PARALLEL LOW-TIME BANDWIDTH PRODUCT FFT-LIKE OPERATIONS. THE PROPER COMBINATION OF ALGORITHMS DESIGN TOGETHER WITH THE HIGH-SPEED ANALOG OPTICAL TECHNOLOGY PROMISES OVER ONE MILLION DATA/SIGNAL POINT REAL-TIME CORRELATION OPERATIONS. A SMALL-SCALE, PROOF-OF-PRINCIPLE EXPERIMENT IS ALSO PROPOSED.
