Spatial, temporal, and frequency diversity structures are analyzed to address the blind equalization problem in the presence of time-variant frequency selective channels. The aim of the paper is to present equalization ...

This paper deals with blind equalization of mobile channels, which are either frequency-selective or multiplicative. The proposed algorithm can be used for channel distortion compensation in diversity systems subject ...

L’objectiu del projecte SETRAM és l’especificació d’algorismes de classificació no supervisada d’informació de mobilitat d’usuaris a partir de dades de posició proporcionades per la xarxa mòbil i/o satèl.lit. En el projecte ...

We propose a verification-based algorithm for noiseless Compressed Sensing that reconstructs the original signal operating on a sparse graph. The proposed scheme has affordable computational complexity and its performance ...

This paper addresses the use of multichannel receivers for blind equalization in TDMA under frequency selective channels and OFDM systems in frequency flat fading channels. A new criteria is proposed for blind equalization ...

We introduce a new family of graph-based source codes that can be regarded as a nonlinear generalization of LDPC codes, and apply them to the compression of asymmetric binary memoryless sources. Simulation results and the ...

This paper introduces a joint bit loading and power allocation algorithm for systems combining bit-interleaved coded modulation (BICM) with multicarrier transmission. The proposed algorithm maximizes the mutual information, ...

We propose a novel scheme for source coding of non-uniform memoryless binary sources based on progressively encoding the input sequence with non-linear encoders. At each stage, a number of source bits is perfectly recovered, ...

In this document, the synchronization algorithms developed during the project are presented and simulated. The studied algorithms are designed for a QS-CDMA system operating in the low SNR regime, i.e., at low Es/No values ...
