Interference is a major limiting factor for wireless communications. When interference is independent and identically distributed (i.i.d.), its statistics is invariant with time. The conventional statistical analysis can be used to mitigate the interferences. However, when the interferences are non-i.i.d., few signal processing techniques are available for mitigating the interferences. The matched filter technology is probably the best signal processing technique. In this presentation, a least cross-correlation criterion based rotation-matched filter is presented that can mitigate the interferences and achieve the optimal signal to interference-plus-noise ratio (SINR). Based on the simulation study it is better than the matched filter by 5∼10 dB.
