Turbo codes are the error-coding schemes applied nowadays in wireless networks. In navalapplications, the information is mostly sent through wireless networks and the data is moreprone to noise. Since very important data has to be communicated, it is nece... see more

Protecting information on various communication media is considered an essential requirement in the present information transmission technology. So, there is a continuous search around different modern techniques that may be used to protect the data from ... see more

In this paper, we consider the transmission of turbo coded symbols in the indoor radio environment. The system isaffected by the intersymbol interference (ISI) caused by the multipath time-delay spread of the transmission medium. To reduce the channel eff... see more

Neste trabalho analisa as estratégias de codificação turbo e convolucional aplicadas ao problema da detecção uniusuário (SuD - Single User Detection) em sistemas de múltiplo acesso DS/CDMA (Direct Sequence/Code Division Multiple Access) considerando canai... see more

An iterative QR-based soft feedback segment interference cancellation (QRSFSIC) detection and decoder algorithm for a Reed–Muller (RM) space-time turbo system is proposed in this paper. It forms the sufficient statistic for the minimum-mean-square error (... see more

Channel decoding is a key feature of a wireless communication standard.It allows reliable data transfer targeting high throu-ghput over unreliable communication channels. Among channel decoding techniques, Turbo codes are frequently adopted in the recent ... see more

In this paper, a predistortion neural network (PDNN) architecture has been imposed to the Sniffer Mobile Robot (SNFRbot) that is based on spatial multiplexed wireless Orthogonal Frequency Division Multiplexing (OFDM) transmission technology. This proposal... see more
