Flexible modulus residue number system for complex digital signal processing
N.W. Wigley, GRAHAM A. JULLIEN · Electronics Letters · 1991
The quadratic residue number system (QRNS) is often used for integer calculation on complex data streams. A finite polynomial ring mapping technique is presented that removes the 4k + 1 prime divisor restriction of the QRNS, albeit with an increase in independent processing channels from two to three.
