Systems and methods cancel or compensate for an echo or noise in borehole communication. The systems and methods provide a downhole tool configured to provide borehole communication via mud pulse telemetry. The downhole tool pulses drilling fluid to generate a first pressure pulse and a second pressure pulse. The first pressure pulse moves upwardly with respect to the downhole component and is encoded with data associated a downhole measurement. A sensor is electrically connected to and in communication with the downhole tool. The first sensor is adapted to detect a characteristic of the second pressure pulse in the drilling mud. A ideal pressure pulse or a correction pressure pulse is generated by a downhole tool or a mud pulse modulator to reduce or cancel noise of the second pressure pulse.
