摘要： A method for modulating data for transmission within a communication system. The method includes establishing a time-frequency shifting matrix of dimension N×N, wherein N is greater than one. The method further includes combining the time-frequency shifting matrix with a data frame to provide an intermediate data frame. A transformed data matrix is provided by permuting elements of the intermediate data frame. A modulated signal is generated in accordance with elements of the transformed data matrix.

摘要： Embodiments may provide a way of communicating via an electromagnetic radiator, or light source, that can be amplitude modulated such as light emitting diode (LED) lighting and receivers or detectors that can determine data from light received from the amplitude modulated electromagnetic radiator. Some embodiments may provide a waveform in the form of chips at a chipping clock frequency that switch a light source between on and off states to communicate via light sources that can be amplitude modulated such as LED lighting. Some embodiments may provide a method of transmitting the waveform via modulated LED lighting. Some embodiments are intended for indoor navigation via photogrammetry (i.e., image processing) using self-identifying LED light anchors. In many embodiments, the data signal may be communicated via the light source at amplitude modulating frequencies such that the resulting flicker is not perceivable to the human eye.

摘要： A process for allowing a CMN-4 equipped Link 16 terminal to enter an active network. After an initial entry command is entered at the terminal at a given current time at the terminal, a number of time slots are identified in which multiple receivers at the terminal have an opportunity to detect an initial entry message (lEM) after the given current time. Each of the receivers is set to detect an lEM during a different one of the identified time slots. When an lEM is first detected by one of the receivers, the current time at the terminal is reset based on the time slot in which the I EM was detected.

摘要： Apparatus and method for acquiring and tracking a data signal are disclosed. Two different CDR circuits are configured to acquire and track data based on two different modulation schemes. While in the acquisition mode, the first CDR circuit may acquire data signal by sampling the signal at a reduced clock rate and handover to the second CDR circuit when a preamble is found. Also in the acquisition mode, the data acquisition and tracking circuit may determine the power level of the preamble signal and dynamically adjust the threshold level for the tracking period upon finding of the preamble.
