Abstract

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
