This paper provides a review of various inter carrier interference cancellation methods used in Orthogonal Frequency Division Multiplexing (OFDM) in the downlink of Long Term Evolution (LTE) and in many other applications. It contains the analysis of different methods, their explanations, areas of implementation, advantages, drawbacks and finally a comparison of the methods has been made. The p...

PURPOSE OF REVIEW This review highlights the recent evidence describing the outcomes associated with fluid overload in critically ill patients and provides an overview of fluid management strategies aimed at preventing fluid overload during the resuscitation of patients with shock. RECENT FINDINGS Fluid overload is a common complication of fluid resuscitation and is associated with increased ...

Mathematics is often described as the study of patterns, some of the most beautiful of which are periodic. In the integers these periodic patterns take the form of arithmetic progressions, i.e., a set of integers which are equally spaced, or have the same common difference. For example, 5, 11, 17, 23, 29 is an arithmetic progression with 5 terms where consecutive terms have a difference of 6. S...

The strong inter-channel cross correlation between stereo received signals creates a problem of non-unique solutions for stereo echo cancellation. To avoid this problem, the addition of inaudible non-linearly filtered received signals to themselves was proposed. However, the convergence of misalignment is still slow even when the affine projection algorithm is used, since strong inter-channel c...

Adaptive echo cancellers with two-path algorithm are applied to avoid the false adaptation during the double-talk situation. In the two-path algorithm, several transfer logic solutions have been proposed to control the filter update. This paper presents an improved transfer logic solution. It improves the convergence speed of the two-path algorithm, and allows the reduction of the memory elemen...

An adaptive iterative decision multi-feedback detection algorithm with constellation constraints is proposed for multiuser multiantenna systems. An enhanced detection and interference cancellation is performed by introducing multiple constellation points as decision candidates. A complexity reduction strategy is developed to avoid redundant processing with reliable decisions along with an adapt...

In the DE-STAR lab, we propose to use phased laser array with photon propellant in order to achieve significantly higher speed for the spacecraft. During the simulation, the laser is sometimes turned off to avoid cancellation of force or acceleration. However, if we shut off the laser accurately, the duration rises and drops even when the launch time is altered slightly, which makes the real im...

This paper presents a new ultra-wideband LNA which employs the complementary derivative superposition method in noise cancellation structure. A pMOS transistor in weak inversion region is employed for simultaneous second- and third-order distortion cancellation. Source-degeneration technique and two shunt inductors are added to improve the performance at high frequencies. The degeneration induc...

Computerized trading controlled by algorithms – “Algorithmic Trading” – has become a fashionable term in investment banking. We investigate a set of Xetra order data to find traces of algorithmic trading by studying the lifetimes of cancelled orders. Even though it is widely agreed that an algorithm must randomize its order activities to avoid exploitation by other traders, we still find system...
