发明名称 STRUCTURE AND METHOD FOR PULSE TELEMETRY
摘要 The specification discloses a mud pulse telemetry technique that uses a number of bits per interval based on parameters of the pulse position modulation system in order to reduce data transfer time in a pulse position modulation system. More particularly, the specification discloses that, depending on parameters of the pulse position modulation such as the minimum-time and the bit-width, it may be possible to decrease overall transmission time by splitting values having a larger number of bits into multiple transmissions with each transmission having a smaller number of bits.
