An Orthogonal frequency part multiplexing suffers from a considerable challenge due to a
high peak to average power ratio (PAPR). Hence, an effective method such as partial …

Vectors are massively used in many domains. Several techniques have been proposed for
comparing two vectors, but they only perform the comparison according to the exact values …
