Abstract

This equipment operator additions / subtractions (72) comprises a plurality of hardware modules adder / subtracter (74, 76, 78) and a plurality of links for transmitting data between these modules, on the one hand, and between inputs (E1, E2, E3, E4, E5, E6) and outputs (S1, S2, S3) of the operator and these modules, on the other hand, according to a predetermined structure for the realization of arithmetic calculations. At least one portion (74, 76, 78) physical modules addition / subtraction of the operator and at least a portion (80, 82, 84, 86) the links between these modules are configurable using at least one programmable parameter (α1, a2, a3, a4, β1, β2, β3), at least between a first configuration wherein the operator (72) finalizes calculation of the real parts of FFT coefficients, a second configuration in which the operator completes a calculating imaginary parts of FFT coefficients, and a third configuration in which the operator performs a calculating metric values ​​pa...
