We present the first full map of the Hα emission from the intermediate-velocity cloud Complex L. Kinematically resolved emission components from the ionized gas reveal a close spatial and velocity correspondence to that of the neutral gas as mapped by 21 cm line observations. Using a simple Gaussian component fitting technique, we compare the details of the emission from the two phases of Compl...

A K-user pseudo-orthogonal (PO) randomly spread CDMA system, equivalent to transmission over a subset of K ′ ≤ K single-user Gaussian channels, is introduced. The high signal-to-noise ratio performance of the PO-CDMA is analyzed by rigorously deriving its asymptotic multiuser efficiency (AME) in the large system limit. Interestingly, the K -optimized PO-CDMA transceiver scheme yields an AME whi...

In this paper, we propose a new partition-based filter for removing mixed high probability impulse and Gaussian noises by extraction of the signals. The proposed filter sorts the elements of sample vector and extracts the signals around the median from sorted signals. The extraction vector is classified into one of M partitions, and a particular filtering operation is then activated. The output...

The aim of this paper is to study the achievable rates for a K user Gaussian interference channels for any SNR using a combination of lattice and algebraic codes. Lattice codes are first used to transform the Gaussian interference channel (G-IFC) into a discrete input-output noiseless channel, and subsequently algebraic codes are developed to achieve good rates over this new alphabet. In this c...

Incoherent imaging via an unmodified full pupil seemingly yields the maximum achievable signal-to-noise ratio (SNR) with respect to a fixed photon budget. Such photon-limited SNR is critical in many scenarios, for example, case of fluorescence microscopy. In this work, we propose general method that achieves better transmitting high spatial frequency information through optical system, without ...

For maximal ratio combining (MRC) diversity over correlated fading channels with Gaussian channel gains, we utilize unitary diagonalization to decorrelate the physical channels into uncorrelated virtual channels to easily obtain the moment generating function (MGF) of the received signalto-noise ratio (SNR). The MGF thus obtained has a compact form and can be universally applied to various popu...
