Orthogonal frequency division multiplexing (OFDM) is a popular method for wireless transmission of data at high rate. To increase the speed of transmission, the input high rate data stream is divided into many small data streams which are then transmitted parallel in OFDM system. The key component of OFDM system is the FFT processor. FFT converts the input time domain signal into frequency doma...

We have proposed a Modified Pure Radix Sort for Large Heterogeneous Data Set. In this research paper we discuss the problems of radix sort, brief study of previous works of radix sort & present new modified pure radix sort algorithm for large heterogeneous data set. We try to optimize all related problems of radix sort through this algorithm. This algorithm works on the Technology of Distribute...

The exploitation of data locality in parallel computers is paramount to reduce the memory traac and communication among processing nodes. We focus on the exploitation of locality by Parallel Radix sort. The original Parallel Radix sort has several communication steps in which one sorting key may have to visit several processing nodes. In response to this, we propose a reorganization of Radix so...

This work describes the design of a double-precision radix-8 divider. Low-power techniques are applied in the design of the unit, and energy-delay tradeoffs considered. The energy dissipation in the divider can be reduced by up to 70% with respect to a standard implementation not optimized for energy, without penalizing the latency. The radix-8 divider is compared with one obtained by overlappi...

43  Abstract— A high performance hardware FFT have numerous application in instrumentation and communication systems. It describes new parallel FFT architecture which combines the split-radix algorithm with a constant geometry interconnect structure. The split-radix algorithm knows to have lower multiplicative complexity than both radix-2 as well as radix-4 algorithm. The split-radix algorithm...

A radix-16 fast Fourier transform (FFT) algorithm suitable for multiply-add instruction is proposed. The proposed radix-16 FFT algorithm requires fewer floating-point instructions than the conventional radix-16 FFT algorithm on processors that have a multiplyadd instruction. Moreover, this algorithm has the advantage of fewer loads and stores than either the radix-2, 4 and 8 FFT algorithms or t...

Kushen (Radix Sophorae Flavescentis) is the dried roots of Sophora Flavescens Ait, alkaloids and flavonoids are the main active constituents of Radix Sophorae Flavescentis. The influence of Radix Sophorae Flavescentis on the activities of CYP450 isoforms CYP2B6, CYP2C19, CYP1A2, CYP2C9, CYP3A4 and CYP2D6 were evaluated by cocktail method. The rats were randomly divided into Radix Sophorae Flave...

There are many causes of root canal failure, among them the most common cause is undiagnosed canal. Mandibular molars typically have two roots mesial and distal. However, sometimes an additional buccally (radix entomalris) or lingually (paramolaris) may be present. Awareness, diagnosis, biomechanical preparation important for successful outcome therapy. This article presents management mandibul...
