Abstract : Four ongoing projects are briefly described. These are: 1. Analysis of the Howells-Applebaum algorithm in the presence of moving interference; 2. The use of lattice filters in adaptive array processors; 3. Stability analysis of LMS adaptive filters; and 4. Adaptive array processors with moving interference treated from the frequency-domain point of view. Conclusions are: the Howells-Applebaum algorithm is so insensitive to interference motion that it is unnecessary to consider such motion in the design; and adaptive array processors based on the frequency-domain approach have a worst performance than those based on time-domain approaches mainly because of the time lag required in the operation of the Fourier transform operation.
