Abstract:
A method for encoding a non-negative integer, for example, representative of MWD/LWD data, includes encoding at least a portion of the integer using at least a first order Fibonacci derived sequence. The remainder of the integer may be encoded using conventional Fibonacci encoding. The invention tends to improve coding efficiency, downhole and surface synchronization, and surface detection.
