In this paper, two novel equalization algorithms applying soft–decision feedback, designed for quaternary phase–shift keying (QPSK) transmission are introduced. The first one uses a matched filter (MF) as a front end and is derived from [1] where it was originally developed for binary transmission. The second one is an improved version of the first, employing a minimum mean–squared error (MMSE)...

Arbitrary ratio sampling rate conversion (SRC) structure using B-spline interpolation is proposed for software defined radio (SDR) in this paper. By combining SRC with SDR’s transmitter/receiver filter, the constraint on SRC reconstruction filter can be relaxed, and an overall computational reduction can be achieved. The mixedwidth B-spline is introduced so that both antiimaging and anti-aliasi...

1 Editorial Current day Hallyu (Korean wave) culture is rapidly spreading throughout Asia and the world, moving from the periphery of global culture towards the center. 'Plastic Surgery Hallyu' has joined K-pop, TV dramas, dancing, and food as one of the pillars of the Hallyu craze, and the Korean Society of Plastic and Reconstructive Surgeons (KSPRS) is showing the world its outstanding result...

The filter generator consists of a linear feedback shift register (LFSR) and a Boolean filtering function that combines some bits from the shift register to create a key stream. A new attack on the filter generator has recently been described by Rønjom and Helleseth [6]. This paper gives an alternative and extended attack to reconstruct the initial state of the LFSR using the underlying subspac...

The increasing number of total joint arthroplasties done on an annual basis, now over one million, along with evolving reimbursement strategies, has helped drive the need for more efficient performance of these cases [1]. This increased the demand for efficiency has led to pursuit of faster, more effective, safer, and cheaper surgical strategies. Soft tissue management is an integral part of to...

A 42 year old male presented with swelling in the right posterior cervical region for a period of 2 months. Palpation revealed a soft, non tender, mobile swelling measuring 2 x 1 cms. An elective excision biopsy was performed. Gross examination showed a yellow to pale brown soft mass. On microscopy, a well circumscribed tumour composed of two populations of cells(uni-vacuolated white adipocytes...
