Abstract
A device configured to perform a stage of circular convolutions in an Overlap-Save Filtered-Bank Multicarrier Communication (OS-FBMC) or Overlap-Save-Block FBMC (OSB-FBMC) receiver and the corresponding method, the stage of circular convolutions comprising P circular convolutions operated between subsets of input samples and frequency domain responses of a frequency shifted version of a prototype filter associated to an FBMC modulation having Ccoefficients, with P an integer greater than one, the device comprising at least one Finite Impulse Response filter implemented in the form of a transposed direct filter having at least C−1 taps numbered p=−Δ+1 to p=Δ with wherein the multiplier coefficient of each tap p within the set of taps−Δ+1; 0has an equal absolute value to the multiplier coefficient of tap (1−p). An FBMC equalization and demodulation unit or an FBMC receiver comprising the device.
