Abstract: A receiver receives communications over a communication channel, which may distort an incoming communication signal. In order to counter this distortion, the frequency response of the receiver is manipulated by adjusting several parameters. Each parameter controls at least a portion of the frequency response of the receiver. The optimal values for the parameters are determined by modifying an initial set of values for the parameters through one or more stochastic hill climbing operations until a performance metric associated with the receiver reaches a local optimum. The modified values are displaced through one or more mutation operations. The stochastic hill climbing operations may subsequently be performed on the mutated values to generate the final values for the parameters.

The system also includes a mobile communication device including an application having a calendar feature that identifies times/days in which the renal failure therapy treatment is scheduled to be performed.

At a designated time before the next scheduled renal failure therapy treatment, the application causes a display interface of the personal mobile communication device to display a prompt for medical information. When the medical information is not received before the next scheduled renal failure therapy treatment, the application causes the home therapy machine to delay a start of the next scheduled renal failure therapy treatment.
