    • 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.
    • A代码指定由脉冲传输系统发送和接收的脉冲的特性。 本发明提供了在脉冲特征值范围布局中定义不可允许区域的方法,使得在生成代码时可以考虑不允许的区域。 根据脉冲特征值范围布局或一个或多个其他脉冲的特征值,使用各种方法来定义不允许区域。 各种排列适应时间和非时间脉冲特性之间的差异。 方法寻址指定固定值的特征值布局和指定非固定值的特征值布局。当生成描述脉冲的代码时,考虑在脉冲特征值布局内定义的不允许区域,使得代码元素值不映射到不允许的脉冲 特征值。

    • Time is transferred from an ultra wideband (UWB) transmitter to UWB receiver by transmitting a signal structure having an associated timing reference point together with a time value for the timing reference point. The UWB receiver receives the timing signal structure by synchronizing a receiver time base to the signal structure, demodulating the time value information, and using the demodulated time value information to set a receiver clock value. Propagation delay information is used to adjust the receiver clock value by advancing the receiver clock value to account for the propagation delay. In one embodiment, propagation delay is determined from a known distance between the transmitter and receiver. In another embodiment, the transmitter and receiver are part of a two-way link wherein propagation delay is measured by round trip timing measurements.
    • 通过发送具有相关联的定时参考点的信号结构以及定时参考点的时间值,将时间从超宽带(UWB)发射机传送到UWB接收机。 UWB接收机通过将接收机时基同步到信号结构,解调时间值信息,并使用解调时间值信息来设置接收机时钟值来接收定时信号结构。 传播延迟信息用于通过提高接收机时钟值来考虑传播延迟来调整接收机时钟值。 在一个实施例中,从发射机和接收机之间的已知距离确定传播延迟。 在另一个实施例中,发射机和接收机是双向链路的一部分,其中通过往返定时测量来测量传播延迟。
