Claim Text:
1. A method for transmitting data from a downhole component, the method comprising: receiving a fluid pulse telemetry signal at a receiver, wherein receiving includes measuring a borehole fluid pressure by the receiver at a selected sampling rate and estimating the telemetry signal transmitted through the fluid based on the sampled fluid pressures; measuring, by at least one pump stroke sensor, operation of a pump configured to advance at least a portion of the borehole fluid through the borehole, wherein measuring includes detecting one or more individual events related to movement of one or more components of the pump; generating a digital pump stroke signal for each of the one or more individual events, each digital pump stroke signal including a digital time value associated with one of the one or more individual events; and transmitting the telemetry signal and each digital pump stroke signal to a signal processing unit, the signal processing unit configured to remove a pump signature from the telemetry signal.
