(EN) A multi−carrier filter for a wireless communications system employing a multi−carrier signal. The multi−carrier filter includes a first mechanism for receiving the multi−carrier signal and extracting carrier signal components A second mechanism filters the carrier signal components and outputs a demodulated and filtered multi−bandwidth signal. In the specific embodiment, the first mechanism includes a rotator. The multi−carrier signal is a 3x bandwidth multi−carrier signal which has three carrier components. The three carrier components include a center carrier, a left carrier, and a right carrier. The center carrier, the left carrier, and the right carrier are separated by approximately 1.25 MHz. The rotator is a lookup table rotator that includes a mechanism for selectively rotating the multi−carrier−signal clockwise or counter clockwise and outputting the left carrier or the right carrier, respectively.
