Abstract:
In at least some embodiments, a method is provided. The method includes receiving samples from a first input channel and a second input channel. The method further includes controlling commutators to selectively switch samples between the first and second input channels for input to a radix-2 butterfly. The method further includes continuously activating the radix-2 butterfly while processing samples received from the first input channel followed by samples received from the second input channel.
