METHODS AND APPARATUS FOR ADAPTIVELY PERFORMING ALGEBRAIC INTERFERENCE CANCELLATION |
摘要 |
An adaptive alge aic interference cancellation technique for canceling interference from a signal of interest received by an array of antenna elements involves: generating a set of antenna element signals that reflect reception of the signal of interest and interference at the respective antenna elements; adaptively determining the direction of one or more interference sources received with the signal of interest; for each interference source, constructing a directional interference vector corresponding to the direction of the interference source; computing a projection operator that transforms each directional interference vector to a zero vector; applying the projection operator to the antenna element signals to remove interference from the antenna element signals; and restoring the signal of interest by individually compensating the antenna element signals for distortion to the signal of interest cause by applying the projection operator.
