| Abstract |
| Nonlinear effects of the Normalized Least Mean
Square (NLMS) algorithm are studied in the presence of
multipath and severe narrowband interference, for applications
where there is no direct reference for the interfering signal. The
nonlinear characteristics of the adaptive equalizer are used to
generate a reference signal for the interference from the
instantaneous error signal. The adaptive coefficients are
optimized such that the width of the notch is minimized in order
to reduce signal distortion. The bit error rate improvement is
quantified as a function of input SINR, multipath characteristics,
and NLMS filter parameters. |
