Abstract: An example apparatus includes: memory having a terminal, the memory to store machine-readable instructions and adjacent channel leakage data; and programmable circuitry having a terminal coupled to the terminal of the memory, the programmable circuitry to execute the machine-readable instructions to: determine a range of out-of-band frequencies responsive to adjacent channel leakage ratio data; generate weight values responsive to electromagnetic emissions within the range of out-of-band frequencies of a first signal; modify a pre-distortion function responsive to the weight values; and apply the modified pre-distortion function to generate a second signal, the second signal to exhibit fewer emissions in the range of out-of-band frequencies than the first signal during transmission.
