The division by a constant D is equivalent to the multiplication by its reciprocal. Since the denominator is constant, so is its reciprocal (1/D). Thus it is possible to compute the value of (1/D) once at compile time, and at run time perform the multiplication N·(1/D) rather than the division N/D. In floating-point arithmetic the use of (1/D) presents little problem, but in integer arithmetic the reciprocal will always evaluate to zero (assuming D > 1). WebThe above algorithm is called the fixed-point minimum error entropy (FP-MEE) algorithm. The FP-MEE algorithm can also be implemented by using the forgetting recursive form [194], i.e., (4.105) where (4.106) This is the recursive fixed-point minimum error entropy (RFP-MEE) algorithm.
