摘要： An interference canceller comprises a composite interference vector (CIV) generator configured to produce a CIV by combining soft and/or hard estimates of interference, an interference-cancelling operator configured for generating a soft projection operator, and a soft-projection canceller configured for performing a soft projection of the received baseband signal to output an interference-cancelled signal. Weights used in the soft-projection operator are selected to maximize a post-processing SINR.

摘要： A method for correcting RDS demodulation in a vehicle radio system including a digital core with an RDS demodulation block, a numerically controlled oscillator, a digital mixer that mixes the input signals with the output of the numerically controlled oscillator, a low-pass filter for recovering baseband RDS signals including a sequence of symbols, and a phase-estimating block configured to estimate a phase deviation of the baseband signal. The method including a first correction acting, depending on the estimation of the phase deviation of the baseband signal, on a phase equalizer, downstream of the low-pass filter, in order to cancel out the phase deviation, and optionally a second correction forming a feedback loop and acting on the numerically controlled oscillator depending on the drift in the phase deviations of the baseband signal.

摘要： A method is disclosed to calculate combining weight vectors associated with a received composite information signal comprising at least one data stream transmitted from at least four antennae. The method starts with computing a parametric estimate of an impairment covariance matrix including at least a first impairment term associated with common pilots deployed by the antennae. The first impairment term captures effects of interferences of the common pilots. The impairment covariance matrix further includes a data covariance term capturing effects of the at least one data stream and an interference term caused at least partially by contribution of thermal noise of receiver branches. The impairment covariance matrix includes a second impairment term associated with at least one dedicated pilot. Then the method computes the combining weight vector using the computed impairment covariance matrix. A network device performs such method is also disclosed.

摘要： Aspects of the present invention include methods, systems, and computer-readable medium for canceling interference in wireless communication. The method includes receiving wireless CDMA communication signals using one or more antennas at least from a first entity via a first communication channel and a second entity via a second communication channel, determining a set of known characteristics associated with the first entity, the first set of characteristics comprising a first signal strength, a first synchronization information, and an first channel identification information, and determining an aggregate signal matrix based on signals received from at least the first entity and the second entity. The method further includes determining a covariance matrix associated with the aggregate signal value, determining a reference signal matrix based on the set of known characteristics, calculating an interference matrix by subtracting the reference signal matrix from the covariance matrix, and removing the interference estimation from the communication signals.
