Abstract: A well pump system can include piping having an end positioned proximate to an entrance end of a borehole (e.g., a water well), and piping having an end positioned proximate to an opposing end of the borehole. A connector can couple the piping together, where the connector has ports for aligning the piping to form a longitudinal passage. The well pump system may further include a valve in the piping that can open and close the longitudinal passage with an actuator to be actuated from the entrance end of the borehole. A pump may be coupled to the piping, and a rod can be used to operate the pump. An end of the rod can be positioned between the opposing end of the borehole and the valve and connected to a second rod inserted through the longitudinal passage when the valve is open to operate the pump.

The method comprises the following steps: (1) generating a plurality of I and Q components of symbols by mapping an input bit stream comprising a plurality of digital codewords into a QAM constellation; (2) selecting a passband or a baseband mode; and (3) generating an analog output signal in the passband or baseband mode. The step of selecting the passband or the baseband mode depends on the complexity of QAM constellation. If QAM constellation includes less than 64 QAM plant points, the passband mode is selected, and if QAM constellation includes more than 64 QAM plant points, the baseband mode is selected.
