The polynomial expansion (PE) multiuser detector (MUD) is a well known iterative approach to approximate the decorrelating or the minimum mean-squared error (MMSE) detectors. The computational complexity for the direct matrix inversion involved with the decorrelating and the MMSE detector is O(K/sup 3/), where K is the number of users. Due to the iterative… (More)

The text at hand presents a principal method for parametric maximum-likelihood channel estimation in fast time-variant frequency selective channels. These channels occur in mobile communications at very high velocities. We approach the problem by estimating the spreading function, which is limited in delay and Doppler frequency and therefore lends itself to… (More)

We target M-ary data sequence estimation over time-variant frequency selective fading channels subject to cochannel interference (CCI). A novel joint reduced state sequence estimator is presented cancelling a dominant interferer by joint detection. It works similar to a Joint M-Algorithm (JMA), but with a metric minimizing the expectation of the Euclidian… (More)

In this paper, a prefiltering approach is taken in order to suppress co-channel interference signals in a frequency selective fading environment. A complex time-variant prefilter results. It rotates the signal space to place the interferer on the axis orthogonal to the detection axis. After the equalizer, a projection on the detection axis is done and a… (More)
