(a) Waveform of bounded CP with jitter for N_DD = 5. The blue-dotted line is the accurate waveform, while the red-solid line contains jitter in pulse width (left) or position (right). The extent of jitter is exaggerated for clarity; (b) Impact of jitter in position or width on the performance of bounded CP pulses.
