Abstract
Disclosed are methods and apparatus for optimizing digital pre-distortion associated with a network device. The digital signal processing apparatus in a communication network may comprise at least one processor and at least one memory having computer program code stored thereon and configured, with the at least one processor, cause the digital signal processing apparatus as a network device to perform: splitting an input signal into two or more split signals with different frequencies, the frequency of each of said split signals being different from other said split signals; separating each of the two or more split signals into two or more component signals with different phases; and performing pre-distortion computation by using the component signals to get a pre-distorted signal to be transmitted to a power amplifier.
