    Abstract: A data processor estimates the location of the receiver or estimated range from multicarrier signal. The data processor determines phase compensation data for each ranging subcarrier in the multipath signal. The phase compensation data comprises an adjustment to the estimated range based on a difference between an observed phase of the observed signal vector and a direct path phase of a direct path vector, where the direct path phase is estimated based on one or more prior measurements of a certain observed signal vector when an average amplitude of all (or a majority of) ranging subcarriers converge to substantially the same value.

    Abstract: A communications system including an infrastructure equipment, forming part of a mobile communications network, that transmits and receives data to/from a user device via a wireless access interface using a plurality of Orthogonal Frequency Division Multiplexing (OFDM) subcarriers that extend across a first bandwidth. The infrastructure equipment is configured to transmit repeatedly signals representing a same instance of user device payload data in a second bandwidth less than and within a first bandwidth, and includes a subset of the OFDM subcarriers. The user device is configured to receive one or more of the signals repeatedly transmitted across the second bandwidth, to store in a memory signals representing the repeatedly transmitted signals received across the second bandwidth and to combine the stored signals, and to detect the user device payload data from the combined signals, the user device having been provided with an indication of the second bandwidth.

    Abstract: A data processor data processor is capable of compensating with multipath phase compensation data for a multipath phase error in the at least one subcarrier phase associated with the multipath-impacted signal arising from the transmitted OFDM-like signal. The phase compensation data results in or comprises an adjustment to the estimated range based on a direct signal vector length of a direct path signal and a multipath-impacted signal vector length of a multipath-impacted signal that are determined through observed signals or observed signal vectors of the receiver. The data processor estimates the location of the receiver or estimated range, based on the precise estimate, with the above adjustment for multipath.

    Abstract: A first estimator determines a course estimate of a time of arrival of at least one subcarrier of an OFDM-like multitone signals by adjusting the course estimate of the time of arrival in accordance with a code (first) correlation function. A second estimator determines a precise estimate of the time of arrival of at least one subcarrier of the OFDM-like multitone signals by adjusting the precise time of arrival to align the slope of the subcarrier phases of the OFDM-like multitone signals in accordance with a phase (second) correlation function and consistent with the course estimate of the time of arrival associated with the code correlation function. A data processor estimates the location of the receiver or estimated range based on the precise estimate.

    Abstract: A configurable transceiver and method of operation are disclosed that may dynamically switch between a direct-conversion mode and a direct-sampling mode based, at least in part, upon a frequency component of a receive and/or transmit signal. When in the direct-conversion mode, the transceiver may operate as a direct-conversion transceiver, and when in the direct-sampling mode, the transceiver may operate as a direct-sampling transceiver. For some embodiments, a frequency of the receive signal and/or the transmit signal may be compared with a predetermined frequency threshold value to generate a mode signal, and the mode signal may be used to select between the direct-conversion mode and the direct-sampling mode.
