In the MIMO-OFDM systems, the traditional methods of multi-user detection have some limitations in the rank-deficient scenarios, where the number of supported users exceeds the number of receiver antennas. The multiuser detection (MUD) based on the genetic simulated annealing algorithm (GSAA) is proposed for the rankdeficient problems in the multi-user MIMO-OFDM system. The simulation results s...

sore has appeared among the class of people (not necessarily poor) who, during a heavy rainy season, walked in mud and worked in marshy localities, barefooted. Forty-five inches of rain, mud and marshy conditions?and Naga sore were not previously known to this place. The same thing happened in Benares last summer, when heavy rainfall flooded the area, resulting in mud and marsh so that Naga sor...

Conventional Multi-User Detection (MUD) algorithms for the Multi-Input, Multi-Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) system fail to consider the detection performance and algorithm complexity simultaneously. To address this problem, a new Joint Intelligent MUD (JI-MUD) algorithm that aims to improve the MUD performance of the MIMO-OFDM system and to reduce the complexity ...

A generically applicable hybrid MultiUser Detector (MUD) concept is proposed by appropriately activating different MUDs in consecutive turbo iterations based on the Mutual Information (MI) gain. It is demonstrated that the proposed hybrid MUD is capable of approaching the optimal Bayesian MUD’s performance despite its reduced complexity, which is at a modestly increased complexity in comparison...

The fate of phosphate added to fishponds and the inorganic processes of phosphorus fixation were studied in Israel. Conditions in these ponds are different from those of the more humid climatic zones in having alkaline water and high calcium content. In these condi tions most of the phosphorus added is precipitated as Ca3(P04)2. rctical aspects of this are discussed. The quantitative theobottom...

In this paper, the decision-level data fusion techniques are extended to the multiuser detection (MUD) field. Then two novel MUD algorithms, that is the chairman arbitrating decision-level fusion criterion (CA-DFC) based MUD algorithm and the veto logic decision-level fusion criterion (VL-DFC) based MUD algorithm, are proposed for DS-UWB communication systems. In CA-DFC based method, the chairm...

Submarine mud volcanoes are a significant source of methane to the atmosphere. The Napoli mud volcano, situated in the brine-impacted Olimpi Area of the Eastern Mediterranean Sea, emits mainly biogenic methane particularly at the centre of the mud volcano. Temperature gradients support the suggestion that Napoli is a cold mud volcano with moderate fluid flow rates. Biogeochemical and molecular ...

one of the most important stages in sugar industry that making wastewater and contamination is the water obtained to washing of co2 in mazoot furnace and related pumps. amount of water consumption in this stage is about 30 to 35 percent of weight of sugar beet, so amount of this stream is considerable. mixing of carbon black and water compose the colloid in liquid phase. these colloids do not s...

Recently, the transmission of vector quantization (VQ) over a code-division multiple access (CDMA) channel has received a considerable attention in research community. The complexity of the optimal decoding for VQ in CDMA communications is prohibitive for implementation, especially for systems with a medium or large number of users. A suboptimal approach to VQ decoding over a CDMA channel, dist...
