Abstract
A method for extending the range of acoustic data communication within a fluid enclosed in a pipe, such as in a production petroleum well. The method includes providing an acoustic transmitter and receiver in the pipe separated by a distance d. The transmitter converts the ith data bit into a propagating waveform in the pipe. The propagating waveform is received by the receiver after traversing the distance d. The received propagating waveform for the given data bit is then compensated for dispersion using an adaptive process to find the best statistical fit between the dispersed signal and the known signal shape.
