Abstract :
We propose an adaptive minimum variance equalizer, which is able to recover the transmitted symbols even in the presence of severe cochannel interference (CCI) or adjacent-channel interference (ACI). Under the assumption that the interference exhibits a different symbol rate from the desired signal, the proposed equalizer can mitigate CCI/ACI without requiring knowledge of the channel impulse response of the interference.
