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： A method for mitigating interference in impulse radio communication conveying a message from a transmitting station to a receiving station. The method comprises the steps of: (a) conveying the message in packets; (b) repeating conveyance of selected packets to make up a repeat package; and (c) conveying the repeat package a plurality of times at a repeat period greater than twice the occurrence period of the interference. The communication may convey a message from a proximate transmitter to a distal receiver, and receive a message by a proximate receiver from a distal transmitter. In such a system, the method comprises the steps of: (a) providing interference indications by the distal receiver to the proximate transmitter; (b) using the interference indications to determine predicted noise periods; and (c) operating the proximate transmitter to convey the message according to at least one of the following: (1) avoiding conveying the message during noise periods; (2) conveying the message at a higher power during noise periods; (3) varying error detection coding in the message during noise periods; (4) retransmitting the message following noise periods; (5) avoiding conveying the message when interference is greater than a first strength; (6) conveying the message at a higher power when the interference is greater than a second strength; (7) varying error detection coding in the message when the interference is greater than a third strength; and (8) retransmitting a portion of the message after interference has subsided to less than a predetermined strength.

摘要： A system and method are provided that can detect any part of a multipath impulse radio signal. More specifically, the method compares a template pulse train and the multipath impulse radio signal to obtain a comparison result. The system performs a threshold check on the comparison result. If the comparison result passes the threshold check, the system locks onto any part of the multipath impulse radio signal including a direct path part and at least one multipath reflection part. The system may also perform a quick check, a sychronization check, and/or a command check of the multipath impulse radio signal.

摘要： A coding method, specifies temporal and/or non-temporal pulse characteristics, where pulse characteristic values are relative to one or more non-fixed reference characteristic values within at least one delta value range or discrete delta value layout. The method allocates allowable and non-allowable regions relative to the one ore more non-fixed references. The method applies a delta code relative to the allowable and non-allowable regions. The allowable and non-allowable regions are relative to one or more definable characteristic values within a characteristic value layout. The one or more definable characteristic values are relative to one or more characteristic value references. In addition, the one or more characteristic value references can be a characteristic value of a given pulse such as a preceding pulse or a succeeding pulse.
