HoBi-Like Pestivirus Is the Most Frequently Detected Pestivirus in Cattle Across Different Regions of Brazil. [PDF]
Transbound Emerg DisPestiviruses are major viral pathogens of cattle worldwide, causing substantial economic losses and posing persistent challenges to animal health and productivity. Brazil hosts the world’s largest cattle population and represents a strategic setting for the emergence and maintenance of bovine pestiviruses.

Adaptive Blind Chip-Level Multiuser Detection in Multi-Rate Synchronous DS-CDMA System with Partial Loading [PDF]
, 2004 This paper addresses an adaptive blind multiuser detection strategy for a multi-rate direct sequence CDMA downlink channel. Specifically, two chip-level equalisation schemes, using either variable spreading length (VSL) or multi-code (MCD) multi-rate ...

Blind Chip-Rate Multiuser Equalisation
, 2003 This paper addresses blind multiuser detection in a DS-CDMA downlink channel. The synchronous users are separated by re-establishing orthogonality of their spreading sequences in a common chip-rate equaliser.

A Blind Synchronous Multi-User DS-CDMA Equaliser With Partial Loading [PDF]
, 2004 In this paper, we propose a blind multiuser detection scheme in a direct sequence CDMA downlink scenario by means of a chip-level equaliser, which can be updated even if not all possible users are active, i.e. the system is partially loaded.

Blind Near-MAP Selection Diversity With Multiuser Detection for Multiuser OFDM [PDF]
IEEE Signal Processing Letters, 2006 This letter proposes a receiver algorithm for orthogonal frequency division multiplexing (OFDM) with receiver diversity that uses a new multiuser generalization of the maximum a posteriori probability (MAP) selection diversity combining followed by successive interference cancellation with least-square projection for multiuser detection.

A Low-Complexity Blind Multiuser Receiver for Long-Code CDMA
EURASIP Journal on Wireless Communications and Networking, 2004 Receivers for long-code systems are for computational reasons usually based on simple matched-filter techniques, and hence suffer from multiaccess interference.

Semi-blind and group-blind multiuser detection for the MC-CDMA uplink [PDF]
2004 IEEE 59th Vehicular Technology Conference. VTC 2004-Spring (IEEE Cat. No.04CH37514), 2005 In this contribution both semi-blind and group-blind multiuser detectors designed for uplink MC-CDMA systems are investigated in conjunction with different spreading codes. In the investigated scenario Walsh codes are shown to outperform both Gold codes and Zadoff-Chu codes.

Blind Multiuser Detection for Long-Code CDMA Systems with Transmission-Induced Cyclostationarity
EURASIP Journal on Wireless Communications and Networking, 2005 We consider blind channel identification and signal separation in long-code CDMA systems. First, by modeling the received signals as cyclostationary processes with modulation-induced cyclostationarity, long-code CDMA system is characterized using a time ...

Subspace blind adaptive detection for multiuser CDMA [PDF]
IEEE Transactions on Communications, 2000 Direct adaptive realizations of the linear minimum mean-square error (MMSE) receiver for direct-sequence code-division multiple access possess the attractive feature of not requiring any explicit information of interference parameters such as timing, amplitudes, or spreading sequences; however, they need a training sequence for the desired user ...
