We consider the problem of designing demodulators for linear vector channels with memory that use reduced-size trellis descriptions for the received signal. We assume an overall iterative receiver, and for the parts of the signal not covered by the trellis description, we use interference cancelation based on the soft information provided by the outer decoder. In order to reach a trellis descri...

For wideband speech signal, if traditional noise cancelation algorithms are adjusted, it can be operated wrong way since unvoiced speech is similar as white Gaussian noise and high frequency on voiced speech that is over than MVF is also similar as noise in the presence of noise circumstance. So when speech signal is damaged by these reasons, it cannot be recognized exactly because that each ph...

An implicature i that arises from an utterance U is cancelable if U is consistent with not i. If i is a cancelable implicature, then it is a conversational implicature. However, some particularized conversational implicatures (PCIs) cannot straightforwardly be canceled. Imagine that Mr. X is applying for a philosophy position and his teacher is writing him the following letter of recommendation:

In this article, the authors propose an optimally designed fixed beamformer (BF) for stereophonic acoustic echo cancelation (SAEC) in real hands-free communication applications. Several contributions related to the combination of beamforming and echo cancelation have appeared in the literature so far, but, up to the authors’ knowledge, the idea of using optimal fixed BFs in a real-time SAEC sys...

Persistent activity observed during delayed-response tasks for spatial working memory (Funahashi et al., 1989) has commonly been modeled by recurrent networks whose dynamics is described as a bump attractor (Compte et al., 2000). We examine the effects of interareal architecture on the dynamics of bump attractors in stochastic neural fields. Lateral inhibitory synaptic structure in each area su...

This paper addresses the issues relating to the enforcement of robust stability when implementing the Adaptive Inverse Control (AIC) scheme. In this scheme, an adaptive FIR filter is added to a closed-loop system in order to reduce the output error caused by external disturbances, enhancing the performance achieved by linear time-invariant controllers alone. A Small-Gain-Theorem-based sufficien...

| TURBO-BLAST is a novel multi-transmit multi-receive (MTMR) antenna scheme for highthroughput wireless communications. It exploits a novel space-time coding scheme based on the independent block forward error correction (FEC) codes and space-time interleaving, and a near optimal iterative decoder, for decoding a new generation of space-time codes. The proposed iterative decoder has two decodin...
