Abstract
Techniques to perform adaptive interference cancellation are described. A first apparatus may include a timing recovery module to produce a timing recovery command signal, an interference canceller to receive an interference reference signal and produce an interference canceller signal, and an interpolator to couple to the timing recovery module and the interference canceller, the interpolator to receive the timing recovery command signal and the interference canceller signal and produce an interpolated interference canceller signal. A second apparatus may include a time-domain interference canceller to receive an interference reference signal and produce a time-domain interference canceller signal and a frequency-domain interference canceller to receive the interference reference signal and produce a frequency-domain interference canceller signal. Other embodiments are described and claimed.
