Abstract
Selecting the number of channel taps is an important task for blind equalization of fractionally-sampled FIR communications channels. We present two algorithms for selecting the channel order based on second-order cyclostationary statistics of the received data. The first algorithm uses an asymptotically constant false-alarm rate statistical test. In contrast, existing algorithms rely on rather ad hoc thresholding. The second algorithm extends our existing asymptotically best consistent channel estimator to include order determination.Keywords
