We consider a linear Gaussian noise channel used with delayed feedback. The channel noise is assumed to be an ARMA (autoregressive and/or moving average) process. We reformulate the Gaussian noise channel into an intersymbol interference channel with white noise, and show that the delayed-feedback of the original channel is equivalent to the instantaneous-feedback of the derived channel. By gen...

Most reported multiuser detection techniques for CDMA systems need the channel estimation including the delay spread and the parameters of the multipath channel of the desired user. This paper proposes an intersymbol decorrelating detector that makes use of the cross-correlation matrix constructed by the consecutively received symbols. The proposed detector is attractive for its simplicity beca...

This paper gives a survey and comparison of algorithms for the detection of binary data in the presence of two-dimensional (2-D) intersymbol interference. This is a general problem of communication theory, because it can be applied to various practical problems in data storage and transmission. Major results on trellis-based detection algorithms, previously disparate are drawn together, and pla...

A new look is taken at maximum-likelihood sequence estimation in the presence of intersymbol interference. A uniform receiver structure for linear carrier-modulated data-transmission systems is derived which for decision making uses a modified version of the Viterbi algorithm. The algorithm operates directly on .the output signal of a complex matched filter and, in contrast to the original algo...

Multipath propagation in underwater acoustic channels causes intersymbol interference in the transmission of digital communication signals. An increase of the transmission rate on a multipath channel results in longer intersymbol interference, which ultimately limits the performance of a phase-coherent digital communication system. Recent experimental results, however, show a seemingly surprisi...

Two basic concepts for point-to-point transmission over multiple-input/multiple-output channels with intersymbol interference (MIMO ISI channels) are reviewed and compared. The approaches can be characterized by the way how they deal with multiuser (spatial equalization) and intersymbol interference (temporal equalization). In MIMO orthogonal frequency division multiplexing, temporal equalizati...

In order to determine the performance of wireless data transmssion at high data rates consideration of channel transmission characteristics, intersymbol interference reduction (equalization) channel coding is necessary. In this paper, the combination of a modem combating intersymbol interference by means of decision feedback equalization and reducing bit error probability by a combination of co...

In orthogonal frequency-division multiplexing (OFDM) systems, synchronization issues are of great importance since synchronization errors might destroy the orthogonality among all subcarriers and, therefore, introduce intercarrier interference (ICI) and intersymbol interference (ISI). Several schemes of frequency offset estimation in OFDM systems have been investigated. This paper compares perf...

The paper proposes a new formulation of a minimum mean square error predistortion scheme for multiple-input single-output impulsive ultra-wideband in multiple user environment. For the performance evaluation, scenarios CM1 and CM3 of the IEEE 802.15.3a channel model are considered. Results show that such a scheme has a good trade-off between intersymbol interference and multiple access interfer...
