Abstract:
Preparing data for transmission includes determining bit loading per frequency bin based on channel estimation data to create a data symbol, performing a Fast Fourier Transform (FFT) on the interleaved data symbol array, mapping FFT data output sub-channel to a frequency bin to provide frequency mapped data, and performing an Inverse Fast Fourier Transform (IFFT) on the frequency mapped data to provide IFFT frequency mapped data suitable for transmission using one-dimensional amplitude modulated ultra wideband impulses representing the IFFT frequency mapped data. To recover the data a reverse process is used.

International Classification:
G02B 600
US Classification:
385 18
Abstract:
A system for processing an optical signal includes a reflector that reflects an input optical signal to a selected one of a number of output waveguides and reflects a reference optical signal associated with the input optical signal. A detector detects a position coordinate of the reference optical signal. A memory coupled to the detector stores an expected position coordinate for the reference optical signal. A controller coupled to the memory generates a control signal based upon the position coordinate detected by the detector and the expected position coordinate stored in the memory. An actuator coupled to the reflector positions the reflector in response to the control signal.
Systems And Methods For Determining Operator Location To Ensure Approved Operation Of Work Machines
A system for determining a location of a work machine operator relative to a work machine comprises a machine controller, a radio frequency receiver, and an infrared transmitter unit. The unit comprises a plurality of infrared transmitters configured to generate infrared signals that collectively divide a 360-degree area around the infrared transmitter unit into a plurality of zones. A remote controller remote from the work machine, which comprises a radio frequency transceiver and an infrared receiver, is configured to receive the infrared signal generated by at least one of the plurality of infrared transmitters. The remote controller has a computer system which is configured to decode information within the one or more infrared signals to determine whether the operator is in an approved zone. The computer system enables the radio frequency transceiver to communicate with the radio frequency receiver upon determining that the operator is in the approved zone.
