Claim One:
1. A wireless communication device, comprising: a transmitter configured to transmit a transmit signal; a receiver configured to receive a receive signal; and an interference estimator configured to: generate a first kernel including a first mapping function of the transmit signal and a second kernel including a second mapping function of the transmit signal, the second mapping function being different from the first mapping function; perform one or more cascade estimations for a first portion of the transmit signal using the first kernel, and a following second portion of the transmit signal using both the first and the second kernels to adapt a first filter weight of a set of filter weights based on the first kernel for the first portion of the transmit signal, and to adapt the first filter weight and a second filter weight of the set of filter weights based on the first and the second kernels for the second portion of the transmit signal; and generate one or more interference cancellation signals to reduce interference within the receive signal based on the first and second adapted filter weights.
