摘要： Described herein are architectures, platforms and methods for implementing a direct estimation of a transmitter's position based upon raw radio frequency (RF) signals that are received by a portable device. A mathematical operation such as a maximum-likelihood estimation (MLE) algorithm, which utilizes collected snapshots from the received raw RF signals as variables, is implemented to perform direct estimation.

摘要： A radio communication apparatus includes a variable directivity antenna and a control unit and performs radio communication with another radio communication apparatus. The control unit calculates a position of the another radio communication apparatus by measuring a distance to the another radio communication apparatus and measuring directivity of the another radio communication apparatus by switching directivity of the wave of radio communication using the variable directivity antenna with a MEMS switch. Moreover, the control unit controls the output of the variable directivity antenna according to the calculated position of the another radio communication apparatus.

摘要： Beamforming is a critical element of 5G and especially 6G, but currently requires a series of time-consuming and resource-consuming messages. Disclosed are procedures by which base stations can transmit a phased beam pulse, having a phase that varies with angle, so that each user device can measure the received phase of the pulse and thereby determine its angle relative to the base station. Each user can then sequentially inform the base station of its orientation relative to the base station, or can append that information to another message such as an initial access message or an acknowledgement, for example. The user device and the base station can then exchange messages in narrow beams aimed at each other according to the alignment angle. Also disclosed are procedures to economically generate the wide-angle phased beam by combining overlapping beams of various phases.

摘要： Multiple radio transmissions are processed to determine, for each of a number of directions of arrival of the radio transmissions, a most direct direction of arrival, for example, to distinguish a direct path from a reflected path from the target. In some examples, the radio transmissions include multiple frequency components, and channel characteristics at different frequencies are compared to determine the direct path.

摘要： Aspects of the present disclosure may compensate for cyclic shift delays (CSD) in transmitted signals when estimating angle of arrival information of a wireless signal transmitted by a transmitting device. In some aspects, a receiving device may determine a presence of CSD in the wireless signal, and estimate an angle of arrival of the wireless signal based at least in part on the presence of CSD. For example, the receiving device may determine a first tap of the wireless channel based at least in part on the CSD. The receiving device may then determine a phase difference of the wireless signal between a plurality of antennas of the receiving device based on the first tap of the wireless channel. The receiving device may estimate the angle of arrival of the wireless signal based on the phase difference.

摘要： The present invention relates to an apparatus for estimating an arrival-angle of a reception signal and a beam-forming apparatus in a radio wave receiver, such as radar. More specifically, the present invention relates to an apparatus for accurately estimating an arrival-angle of a reception signal, or an apparatus for performing the beam-forming of a reception signal by using a multi-reception array antenna, by using a reference value that is obtained by calculating the degree of distortion of the magnitude and phase of a signal for each reception angle.
