2005 journal article

Adaptive optimization of least-squares tracking algorithms: With applications to adaptive antenna arrays for randomly time-varying mobile communications systems

IEEE TRANSACTIONS ON AUTOMATIC CONTROL, 50(11), 1749–1760.

By: R. Buche n & H. Kushner*

author keywords: adaptive antennas; mobile communications; randomly time-varying channels; stochastic approximation; tracking time-varying parameters
TL;DR: Another adaptive loop is added that tracks the optimal value of /spl alpha/ and greatly improves the operation when the environment is randomly time-varying and the algorithm is practical and can improve the performance considerably. (via Semantic Scholar)
