Abstract: Disclosed is a system and method for power line control of devices. The system operates in two modes. In mode one, the system operates on an open loop architecture with a controller generating a sinusoidal wave using a crystal oscillator. Control information is added to the sinusoidal wave by alternating the output of two phase shifted waves which have the same frequency and amplitude to form a control signal. The resulting control signal is sent on a power line. The control signal is received using a crystal filter, decoded and converted to executable instructions for the devices and data parameters for sensors. In mode two, the system operates on a hybrid open loop/closed loop architecture where devices are jointly controlled by the controller and the sensors.

Abstract: A system and method of DFT-S-OFDM modulation is provided that uses a set of frequency domain patterns. For a given transmitter, for a set of DFT-S-OFDM symbols, the frequency domain pattern changes according to a time domain hopping pattern. Advantageously, the time domain hopping patterns are defined to allow only a certain amount of overlap, for example for only one DFT-S-OFDM symbol, between any two time domain hopping patterns. This functions to reduce the effect of a collision, when two transmitters use the same frequency pattern, they will do so only for part of the overall transmission. Optionally, frequency domain spectral spreading is used in the transmitter. This can further reduce the PAPR. In the receiver, successive interference cancellation may be employed to reduce the effect of colliding transmissions.
