Abstract
QPSK or 16QAM modulation technology is used in upstream channel of HFC bi-direction net. In this study the CMRLS and the CMFTF known as high efficient nonlinear arithmetic are applied in the narrow band interference suppression. After analysis with multi-frequency interference the simulation results are shown that CMFTF performance is the nearly same as the CMRLS algorithm, but less computation, so the CMFTF is considered as the best algorithm.
