Interference Cancellation of AM Narrowband Interference Signals
— In this paper, we consider an overlay system where narrowband AM signals interfere with a broadband multicarrier system [1]. To reduce the effect of the AM narrowband interfere...

A Simple Improvement to the Viterbi and Viterbi Monomial-Based Phase Estimators
Abstract—It is well known that the Viterbi and Viterbi MonomialBased Phase Estimator, which includes the Mth Power Estimator, performs poorly for cross QAM signals. However, it i...
