摘要： A coding method specifies characteristics of pulses of a pulse train including, but not limited to, time position, polarity, amplitude, width, and type. Pulse characteristics are specified, for example, by mapping code elements to value range layouts, discrete value layouts, or to combination value range/discrete value layouts. A code element can be an integer of floating point value, and can specify two or more characteristics of a pulse. Various approaches are described. A value range layout can be subdivided into components, sub-components of components, where each sub-component can be a sub-component of the component, or a smaller component of the sub-component (or an even smaller component of the smaller component, ad infinitum). Methods are provided for defining non-allowable regions within value range layouts to be considered when generating a code. Various approaches address characteristic value layouts specifying fixed values and characteristic value layouts specifying non-fixed values, and accommodate differences between temporal and non-temporal pulse characteristics. The method can require codes to satisfy predefined criteria. 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 set of piconets and corresponding methods and computer programs may reduce contention time between piconets. In one embodiment, a seven-length code architecture may be used with group(s) of bands so that contention time cannot exceed 1/7 of the time. Up to seven different bands can be used within each group. When less than seven bands are used (e.g., three or six), at least one of the bands may be assigned to more than one dwell time during a time span. Alternatively, each dwell time within the time span may be assigned to a different band. The state may be changed as needed or desired. Substitution of extra bands may also be used. Using either scheme (repeated bands or changing states), a prime-number architecture can be used with a non-prime number of different bands. Simultaneous communications using at least two bands within a piconet may be used.

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 system, method and computer program product for positioning pulses, including positioning pulses within a specified time layout according to one or more codes to produce a pulse train (108) having one or more predefined spectral characteristics where a difference in time position between adjacent pulses positioned to produce a spectral characteristic differs from another difference in time position between other adjacent pulses positioned to produce the spectral characteristic. The present invention may include shaping a code spectrum according to a spectral template in order to preserve a pre-defined code characteristic. A pre-defined code characteristic can include desirable correlation, or spectral properties. A transmitter incorporating the present invention can avoid transmitting at a particular frequency. Similarly, a receiver can avoid interference with a signal transmitting at a particular frequency. A radar system, can avoid a radar jammer attempting to jam a particular frequency.

摘要： A code, comprised of at least one code element, specifies at least one non-temporal characteristic of at least one pulse. A code element can be mapped to a value within a layout, comprising a range of pulse characteristic values, divided into components and sub-components. The code element can be an integer, or a floating-point number, and may be used in conjunction with an absolute or relative offset value. The code element values can be subdivided into parts, that individually, or in combination, specify non-temporal pulse characteristics. The code element can be used to specify a number of characteristics of a pulse, including pulse polarity; pulse amplitude; pulse width; pulse type; and pulse position in time. The type of the pulse indicates whether the pulse is a square wave pulse, sawtooth pulse, Haar wavelet pulse, gaussian monopulse, doublet pulse, triplet pulse, or set of wavelets.
