Abstract: In a system, known digitizer signals (known analog signals or digital representations of known analog signals) are generated. The known digitizer signals are input into digitizers (analog-to-digital converter (ADCs) or digital-to-analog converter (DACs)) to output generated digitizer signals (generated digital representations or generated analog signals). The generated digitizer signals are analyzed in relation to the known digitizer signals to generate coupling coefficients, which can be either scalar quantities or finite-impulse-response (FIR) filter functions. Subsequent digitizer signals are generated. The subsequent digitizer signals are modified using the coupling coefficients to generate modified digitizer signals according to formulae. The modified digitizer signals are used directly as digital representations, or are input to the DACs to output modified analog signals that substantially match subsequent analog signals.

Abstract: The various embodiments include methods and apparatuses for cancelling nonlinear interference during concurrent communication of multi-technology wireless communication devices. Nonlinear interference may be estimated using a minimum mean squares interference filter by generating aggressor kernels from the aggressor signals, augmenting the aggressor kernels by weight factors and executing a linear combination of the augmented output, at an intermediate layer to produce intermediate layer outputs. At an output layer, a linear filter function may be executed on the intermediate layer outputs to produce an estimated nonlinear interference used to cancel the nonlinear interference of a victim signal.

Abstract: The present invention addresses apparatuses, methods and computer program product for improvement of signaling and procedure for in-device co-existence. An IDC Resolution Timer (IRT) is added at both UE and eNB sides. The IRT starts to run once UE sends IDC indication to eNB. If UE doesn't receive any IDC response from eNB after IRT expires, UE could assume that eNB rejects its IDC indication and UE could start to use other possible methods such as switching off other ISM RAT, or using autonomous denial. If UE receive IDC response from eNB before IRT expires, it will reset the IRT.

Abstract: Systems, methods, and apparatus are described that employ specially designed interference patterns to build an in-band side channel without degrading the effective throughput of the main channel. Transmitter and receiver pairs implement a two-stage dynamic interference mitigation scheme based on the partial connections in limited dimension MIMO interference channels. The first stage determines the stream assignments and the subspace constraints for beamforming vectors and zero-forcing vectors based on the partially connected topology such as the path loss, shadowing and spatial correlation. The second stage determines the beamforming vectors and the zero-forcing vectors based on the instantaneous channel state information over the subspaces obtained from the first stage. In an aspect, a controller device implements the first and second stage and assigns the transmitter and receiver pairs to perform interference alignment using the stream assignments and beamforming and zero-forcing vectors respectively.

The system comprises a receiver (104) for receiving a signal comprising a data packet transmitted over the multipath communication channel (102). The system also comprises a frequency-domain channel estimator (110) that generates a frequency-domain channel estimate (112) based on the received signal. The system further comprises a time-domain channel modeller (114) that receives the frequency-domain channel estimate (112) and generates an estimate of parameters in a time-domain model of the multipath communication channel (102).

Abstract: A receiver includes a constellation processing module and a multi-stage demodulator having a plurality of non-final demodulation stages and a final demodulation stage. The constellation processing module derives a set of centroid-based values from subsets of constellation points associated with a plurality of transmitted signals for input to each of the non-final demodulation stages. Each of the non-final demodulation stages demodulates a group of signals input to the non-final demodulation stage using the set of centroid-based values as constellation points and suppresses residual interference associated with using the set of centroid-based values as constellation points for signal demodulation. The final demodulation stage demodulates a group of modified signals input to the final demodulation stage using the subset of constellation points input to the final demodulation stage to determine a final symbol decision for the plurality of transmitted signals.

Abstract: A method is described that enables a system to estimate the individual times of arrival of multi-path signals components in a received signal (301) while blind to the particular angular response characteristics of an antenna array. Additionally, a system is described that estimates the impulse response (301) estimated for all multi-path signal components without reference to the actual angle of arrival of the signal. The impulse response for the multi-path constituents are directly associated with the time delays on each path, providing delay estimates for each path.
