    Abstract: Systems and methods for using power cycle events to cause a downhole tool to change its operational state and/or transmit a data stream to the downhole tool. In one embodiment, a tool such as a gauge for an ESP is positioned downhole in a well and is configured to receive power from a control unit at the surface of the well. The control unit power cycles the downhole tool to communicate a need to modify the operational state of the tool. The tool may include a non-volatile memory to store an indicator of the tool's current operational state. When the tool is power cycled, the operational state is modified and the indicator is updated. The power cycling may cause the tool to increment through available operational states, or the timing of the power cycles may convey parameters or other operating information to the downhole tool.

    Abstract: Systems and methods for reliably communicating data at high data rates between surface and downhole equipment over a power cable by multiplexing data, modulating the data onto orthogonal carrier frequencies, communicating the modulated carrier signals over the power cable, recovering of the modulated signals, and demodulating the data stream from the recovered signal. One embodiment comprises a system that includes surface equipment connected by a power cable to an ESP system that has a gauge package connected to it. The gauge package uses a high-temperature DSP to perform the data processing associated with OFDM communications.
