摘要： An ultra-wideband communication and/or location system having a plurality of channels, each implementing a respective one of a plurality of predetermined codewords. Within each channel, one or more predetermined pulse repetition frequencies are defined. Within a single UWB system, more than two networks of transceivers may be co-located without mutual interference if each is assigned a unique combination of codewords and spreading factors.

摘要： In an ultra-wideband (“UWB”) receiver, a received UWB signal is periodically digitized as a series of ternary samples. The samples are continuously correlated with a predetermined preamble sequence to develop a correlation value. When the value exceeds a predetermined threshold, indicating that the preamble sequence is being received, a stream of estimates of the channel impulse response (“CIR”) are developed. When a start-of-frame delimiter (“SFD”) is detected, the best CIR estimate is provided to a channel matched filter (“CMF”) substantially to filter channel-injected noise. The time of arrival of the first arriving path is developed from the stream of CIR estimates.

摘要： A method for transmitting data through an analogue channel from an analogue modem to a digital modem includes encoding data inputted to the analogue modem. An encoder encodes data inputted into the analogue modem into corresponding constellation points of a one-dimensional constellation. During initial handshaking a microprocessor in the digital modem computes the constellation points of the constellation so that mid points between adjacent constellation points coincide with mid points between adjacent codec levels. The computed constellation points of the constellation are transmitted along with the value of the largest constellation point and its corresponding codec level to the analogue modem. By selecting the mid points between the constellation points to correspond with mid points between adjacent codec levels the noise margin is significantly enhanced.

摘要： In an ultra-wideband (“UWB”) communication system comprising a pair of UWB transceivers, an asynchronous two-way ranging method for closely estimating the time-of-flight between the transceivers after the exchange of only 3 messages between the transceivers. In an alternate asynchronous two-way ranging method, the time-of-flight between the transceivers may be closely estimated after the exchange of only 4 messages between the transceivers.

摘要： In an RF system comprising a first transceiver (96) and a second transceiver (98), a first transmission, T1, by the first transceiver (96) allows the second transceiver (98) to determine two possible valid angles of arrival, ±θ1, of T1. A second transmission, T2, from the second transmitter (98) to the first transmitter (96) containing θ1 and a bearing, α1, of a known fixed anchor relative to the second transmitter (98), allows the first transmitter (96) to determine two possible valid angles of arrival, ±θ2, of T2. From θ1, α1, θ2, and a bearing, α2, of the known fixed anchor relative to the first transmitter (96), the first transceiver (96) can determine the valid angle of arrival of T2.

摘要： In an ultra-wideband (“UWB”) receiver, a received UWB signal is periodically digitized as a series of ternary samples. During a carrier acquisition mode of operation, the samples are continuously correlated with a predetermined preamble sequence to develop a correlation value. When the value exceeds a predetermined threshold, indicating that the preamble sequence is being received, estimates of the channel impulse response (“CIR”) are developed. When a start-of-frame delimiter (“SFD”) is detected, the best CIR estimate is provided to a channel matched filter (“CMF”). During a data recovery mode of operation, the CMF filters channel-injected noise from the sample stream. Both carrier phase errors and data timing errors are continuously detected and corrected during both the carrier acquisition and data recovery modes of operation. The phase of the carrier can be determined by accumulating the correlator output before it is rotated by the carrier correction. By comparing the carrier phases of two receivers separated by a known distance, d, the angle of incidence, θ, of the signal can be determined.
摘要翻译：在超宽带（“UWB”）接收机中，接收的UWB信号被周期性地数字化为一系列三进制样本。在载波采集操作模式期间，样本与预定的前同步码序列连续相关，以产生相关值。当该值超过预定阈值时，指示正在接收前导码序列，则开发出信道脉冲响应（“CIR”）的估计。当检测到起始帧定界符（“SFD”）时，将最佳CIR估计提供给信道匹配滤波器（“CMF”）。在数据恢复操作模式期间，CMF对来自样本流的信道注入噪声进行滤波。载波相位误差和数据定时误差在载波采集和数据恢复操作模式两者期间连续检测和校正。可以通过在通过载波校正旋转之前累加相关器输出来确定载波的相位。通过比较以已知距离d分开的两个接收器的载波相位，可以确定信号的入射角θ。

摘要： In an ultra-wideband (“UWB”) network, a central location engine (“CLE”) coordinates operation of an anchor access point (“AP”), AP[0], and a plurality of non-anchor AP[x]s. A clock calibration packet (“CCP”) transmission method and related apparatus facilitate normalization of CCP time references reported to the CLE by all APs. Implementing a digital phase locked loop (“DPLL”) in the CLE facilitates clock normalization. Implementing a DPLL in at least the non-anchor AP[x]s facilitates local clock synchronization, and may improve network efficiency by reducing clock synchronization traffic.
