摘要： A method for specifying pulse characteristics applies codes having pre-defined characteristics to a layout. The layout can be sequentially subdivided into at least first and second components that have the same or different sizes. The method applies a first code having first pre-defined properties to the first component and a second code having second pre-defined properties to the second component. The pre-defined properties may relate to the auto-correlation property, the cross-correlation property, and spectral properties, as examples. The codes can be used to specify subcomponents within a frame, and characteristic values (range-based, or discrete) within the subcomponents.

摘要： A coding method for a pulse transmission system specifies temporal and/or non-temporal pulse characteristics according to temporal and/or non-temporal characteristic value layouts having one or more allowable and non-allowable regions. The method generates codes having predefined properties. The method generates a pulse train by mapping codes to the characteristic value layouts, where the codes satisfy predefined criteria. In addition, the predefined criteria can limit the number of pulse characteristic values within a non-allowable region. The predefined criteria can be based on relative pulse characteristic values. The predefined criteria can also pertain to spectral properties and to correlation properties. The predefined criteria may pertain to code length and to the number of members of a code family. The pulse train characteristics may pertain to a subset of the pulse train.

摘要： A code specifies characteristics of pulses transmitted and received by an impulse transmission system. The invention provides methods for defining non-allowable regions within pulse characteristic value range layouts enabling non-allowable regions to be considered when generating a code. Various approaches are used to define non-allowable regions based either on the pulse characteristic value range layout or on characteristic values of one or more other pulses. Various permutations accommodate differences between temporal and non-temporal pulse characteristics. Approaches address characteristic value layouts specifying fixed values and characteristic value layouts specifying non-fixed values. When generating codes to describe pulses, defined non-allowable regions within pulse characteristic value layouts are considered so that code element values do not map to non-allowable pulse characteristic values.

摘要： A system and method for shaping the energy spectrum of a pulse train used by a pulse transmission system. The initial temporal and non-temporal characteristics of pulses comprising the pulse train are established using a designed code or a pseudorandom code and the spectral properties of the pulse train are determined. At least one characteristic of at least one pulse of the plurality of pulses that make up the pulse train are modified or at least one pulse is added or deleted to the pulse train and the spectral properties of the modified pulse train are determined. Whether or not the modification to the pulse train improved the energy spectrum relative to acceptance criteria is determined. The pulse train having the most desirable energy spectrum is selected. The optimization process can also iterate and may employ a variety of search algorithms.

摘要： A method for positioning pulses over time (via a time layout) applies time-hopping codes having pre-defined characteristics. The time layout can be sequentially subdivided into at least first and second time components that have the same or different sizes. The method applies a first time-hopping code having first pre-defined properties to the first time component and a second time-hopping code having second pre-defined properties to the second time component. The pre-defined properties may relate to the auto-correlation property, the cross-correlation property, and spectral properties, as examples. The codes can be used to specify subcomponents within a frame, and positions (range-based, or discrete) within the subcomponents, where the pulses are positioned.

摘要： An improved field emission system and method is provided that involves field emission structures having electric or magnetic field sources. The magnitudes, polarities, and positions of the magnetic or electric field sources are configured to have desirable correlation properties, which may be in accordance with a code. The correlation properties correspond to a desired spatial force function where spatial forces between field emission structures correspond to relative alignment, separation distance, and the spatial force function.
