Abstract
Methods, apparatuses, and systems that receive a communication signal. The communication signal may be split into a first communication signal and a second communication signal. The first communication signal may be zero padded. The zero padded first communication signal may be excursion compensated to generate an excursion compensated signal. The excursion compensating may be performed by fast Fourier transform logic. Zero padding may allow for efficient fast Fourier transform process by ensuring that the length of data frames processed is an integer power of two.

A method comprising:
- receiving a communication signal;
- splitting the communication signal into a first communication signal and a second communication signal;
- zero padding the first communication signal;
- and
- excursion compensating the first communication signal with the second signal to generate an excursion compensated signal.
A method comprising:
- receiving a communication signal;
- splitting the communication signal into a first communication signal and a second communication signal;
- interpolating the first communication signal;
- and
- excursion compensating the first communication signal with the second signal to generate an excursion compensated signal, wherein:
- the interpolating is at a rate maximizes computational efficiency of fast Fourier transform logic of the excursion compensating.
An excursion compensation unit configured to:
- receive a communication signal;
- split the communication signal into a first communication signal and a second communication signal;
- zero pad the first communication signal;
