20090017763 | Dynamic multi-path detection device and method - In one embodiment of the present invention, a dynamic multi-path detection device is disclosed to include at least one narrow-band signal metric estimator responsive to input signal. Each of the at least one estimators measures a particular characteristic of the input signal in a frequency band that is narrower than the overall signal bandwidth and is operative to generate a signal parameter estimate signal. The dynamic multi-path detection device is further disclosed to include a signal metric comparison device responsive to the signal parameter estimate signal(s) and operative to generate a dynamic multi-path indication signal for detecting dynamic multi-path. | 01-15-2009 |
20090023392 | MOBILE COMMUNICATION TERMINAL AND METHOD FOR CONTROLLING ACTIVATION OF MULTI-PATH INTERFERENCE REMOVING APPARATUS - An increase in the power consumption and deterioration of the reception characteristic which can arise as a result of installing a multi-path interference removing apparatus are suppressed. The multi-path interference removing apparatus is operated only in the following cases: a case where a mobile communication terminal is in a communication active state, a case where communication takes place via a base station to which the adaptive modulation and coding technology is applied, a case where the number of reception paths of the mobile communication terminal is two or more paths, a case where the speed of motion of the mobile communication terminal is 60 km/h or less, and a case where the Signal to Interference power Ratio is 8 dB or more. | 01-22-2009 |
20090143017 | METHOD AND DEVICE FOR WIRELESS COMMUNICATION USING MIMO TECHNIQUES - The present invention describes a method of closed loop MIMO communication utilizing implicit or explicit channel state information (CSI) at the transmitter and the receiver. The transmitter performs linear pre-processing (for example, QR decomposition or bi-diagonal decomposition or Jacobi rotations, and/or sporadic SVDs) on a channel matrix, and the receiver mitigates the mutual interference between the streams by performing MMSE processing on the received signals. The MMSE matrix is computed with respect to the processed channel that may estimated by the receiver through preprocessed pilot signals. The transmitters preprocessing is of much lesser cost and complexity than full SVD. | 06-04-2009 |

The system includes a transmitter which includes a data source configured to provide data to be transmitted, a modulator configured to modulate the data, a pre-filter configured to apply a filter to the modulated data generating pre-filtered data, and a transmitter antenna configured to receive the pre-filtered data and to transmit the pre-filtered data, the pre-filter based on a phase compensation topology that is based on channel characteristics between the transmitter and a receiver, the frequency response of the pre-filter based on spectral phase information of the channel such that the frequency response at the receiver is proportional to the magnitude of the channel frequency response. | 03-12-2015 |
20150147976 | REMOTE CONTROL METHODS AND SYSTEMS - Methods and systems are provided for preventing interference from simultaneous data transmissions in a remote control system. A controlled terminal is typically configured to receive control data from a controlling terminal and to transmit feedback data to a monitoring terminal. To prevent interference caused by the simultaneous transmissions of control data and feedback data. The controlling terminal can transmit the control data to the monitoring terminal, which then transmits the control data to the controlled terminal. Such transmission of the control data may be carried out in a way that does not interfere with the transmission of the feedback data. | 05-28-2015 |
20160072531 | Methods and Systems for Support Vector Regression Based Non-Linear Interference Management in Multi-Technology Communication Devices - The various embodiments include methods and apparatuses for canceling nonlinear interference during concurrent communication of multi-technology wireless communication devices. Nonlinear interference may be estimated using a support vector regression interference filter by generating one or more aggressor kernels, augmenting the one or more kernels by weight factors, and executing a regression function of the augmented components, to produce an estimated jammer signals. At an output layer, estimated jammer signals may be linearly combined to produce an estimated nonlinear interference used to cancel the nonlinear interference of a victim signal. | 03-10-2016 |
