A Proposal of QRM-MLD for Reduced Complexity of MLD to Detect MIMO Signals in Fading Environment
IEEE Vehicular Technology Conference, 2006This paper proposes symbol replica candidates reduction type QRM-MLD using simple quadrant detection for 4-by-4 MIMO/SDM system with 16 QAM. Though MLD is known as the optimal SDM signal detection algorithm, its computational complexity is exponential in the number of transmit antennas (van Zeltst et al).

Several experiments have shown that the S0M0-SπM0 MLD increases markedly with reduction in masker bandwidth. However, there are at least two inconsistencies in this result. First, apparently similar experiments conducted by different laboratories have produced quite different results.

Decision feedback MLD for CTDMA system
Proceedings of IEEE International Symposium on Information Theory, 2002A decision feedback maximum likelihood detection scheme (DFMLD) is developed to support code time division multiple access (CTDMA) systems operating in a fully loaded mode. CTDMA systems have been proposed as a candidate for the third generation mobile communication systems to combine the advantages of constant envelope transmission of CDMA and the ...

MLD's and the Phase Angle, Alpha
The Journal of the Acoustical Society of America, 1968This Letter describes two experiments designed to discover the effect of the phase angle, α (the angle between a narrow-band masker and a tonal signal), on binaural detection, and offers an explanation of why they failed to reveal any effect.

Poor fact retrieval is a frequently reported characteristic of children with mathematical learning disability (MLD). To better understand the nature and specificity of poor fact retrieval in MLD, in the present study, we examined eighth graders' accuracy on timed addition and multiplication problems of varying levels of difficulty.

Dynamic MLD analysis with flow graphs
Reliability Engineering & System Safety, 2012Abstract Master Logic Diagram (MLD) depicts the interrelationships among the independent functions and dependent support functions. Using MLD, the manner in which all functions, sub-functions interact to achieve the overall system objective can be investigated.

MLD Modeling and MPC of Hand Manipulation
IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences, 2005Based on hybrid system theory, we propose a modeling and control approach for a multi-contact planar manipulation system, whereby a dexterous manipulation task is formulated as a mixed logic dynamical (MLD) model. The MLD model provides the possibility of carrying out the selection of modes, the timing for mode switching, and the determination of the ...

Journal of Learning Disabilities, 2007
Researchers of mathematics learning disability (MLD) commonly use cutoff scores to determine which participants have MLD. Some researchers apply more restrictive cutoffs than others (e.g., performance below the 10th vs. below the 35th percentile). Different cutoffs may lead to groups of children that differ in their profile of math and related skills,

Effect of Signal Frequency on the MLD for Uncorrelated Noise
The Journal of the Acoustical Society of America, 1972Rabiner, Laurence, and Durlach [J. Acoust. Soc. Amer. 40, 62–70 (1966)] reported that the masking-level difference (MLD) for uncorrelated noise with signals in-phase and reversed in-phase at the ears was independent of signal frequency for frequencies between 150 and 1000 Hz.

Scatter Properties of MLD Mirrors. [PDF]
, 1979 Abstract : A study and development of data processing techniques for spatial scatter intensity data from a MLD mirror was undertaken. Several processing schemes were investigated with the result that processing the data so as to produce a true and scaled polar plot of the scatter field seems to be the optimum way of displaying the information.
