Patent number: 9680547Abstract: A network control device. A wireless communications module receives a plurality of first signals each including information regarding a preferred transmitting beam in a first beam level determined by a communications apparatus. A controller selects a group of communications apparatuses to join a 1-to-many beam training according to the received first signals and selects one or more transmitting beams in a second beam level to be trained. The communications apparatuses in the group have the same preferred transmitting beam in the first beam level and the transmitting beam(s) in the second beam level associates with the preferred transmitting beam in the first beam level. The wireless communications module further uses the transmitting beam(s) in turn to transmit signals to perform the 1-to-many beam training for training the transmitting beam(s) in the second beam level among the group of communications apparatuses at the same time.Type: GrantFiled: May 7, 2015Date of Patent: June 13, 2017Assignee: MEDIATEK INC.Inventors: Chia-Hao Yu, Ming-Po Chang, Jiann-Ching Guey

Patent number: 9667305Abstract: A receiver-transmitter includes active two-face phased arrays comprising transmit-receive modules. Each module includes two radiating elements, a transmitter, two receivers, two isolator switches, mixers and a phase shifter. The two-face phased arrays are either unidimensional or two-dimensional. The arrays are arranged in the horizontal plane at an angle of 75-105° to each other while keeping the capability of all-around looking. The transmit-receive module is provided with an additional phase shifter. Each phase shifter can be permanently connected, via a selector switch, to one of the receivers or to the transmitter, and the transmitter is connected, via a switch and circulators, to the radiating elements. Alternatively, each phase shifter can be connected to the radiating elements with the use of different frequencies and/or with the use of a different signal coding, corresponding to different frequencies and coding of the receivers receiving mode.Type: GrantFiled: December 18, 2013Date of Patent: May 30, 2017Inventor: Evgeny Vyacheslavovich Komrakov

Patent number: 9607603Abstract: An adaptive filter of an adaptive blocking matrix in an adaptive beam former or null former may be modified to track and maintain noise correlation between an input and a reference noise signal to the adaptive noise canceller module. That is, a noise correlation factor may be determined, and that noise correlation factor may be used in an inter-sensor signal model applied when generating the blocking matrix output signal. The output signal may then be further processed within the adaptive beamformer to generate a less-noisy representation of the speech signal received at the microphones. The inter-sensor signal model may be estimated using a gradient decent total least squares (GrTLS) algorithm. Further, spatial pre-whitening may be applied in the adaptive blocking matrix to further improve noise reduction.Type: GrantFiled: September 30, 2015Date of Patent: March 28, 2017Assignee: Cirrus Logic, Inc.Inventor: Samuel P.
