Parallel random sampling with multiprocessor system
K.C. Lo, Alan Purvis · 1993 IEEE International Symposium on Circuits and Systems · 2002
An anti-alias sampling sequence for spectral estimation can be formed by interlacing several additive random sampling sequences. This scheme exploits the trigonometrical symmetry to reduce up to 87% of the multiplications required in computing the first band of frequency components. The whole process, from sampling to computation, can be implemented by a multiprocessor system. With a variable threshold, a relatively weak signal can also be recovered.>
