A differential 2MSK receiver, based on regeneration of the MSK signal component with larger amplitude in the receiver, was designed and analysed. The proposed receiver structure is relatively simple and has only 1dB lower power efficiency than the optimal maximum likelihood sequence estimator. Sensitivity of the receiver to non-optimum amplification of the received signal, to error in the symbo...

svm یک تکنیک مدولاسیون شناخته شده برای مبدل های قدرت با توان متوسط و ولتاژ بالا می باشد. باید توجه داشت که تمام فرآیند مدولاسیون برای هدف پیاده سازی می تواند زمان بر باشد که علت آن یافتن موقعیت بردار مرجع به علاوه اجرای محاسبات ضروری برای مدولاسیون می باشد. علاوه بر آن با افزایش تعداد سطوح در مبدل های چند سطحی، زمان این محاسبات برای svm های متداول افزایش می یابد. این مقاله یک تکنیک مدولاسیون را...

In acute myeloid leukemia (AML) the subset with complex karyotype (CK) is traditionally regarded as the worst prognostic group. However, ≥ 3, ≥ 4, or ≥ 5 abnormalities have been variably used for its definition. Recently, monosomal karyotype (MSK) was suggested to indicate an even inferior outcome. We tested which definition fits best to identify the most unfavorable subgroup. After excluding p...

BACKGROUND Musculoskeletal (MSK) symptoms are common within primary care but some general practitioners (GPs)/family physicians do not feel comfortable managing these symptoms, preferring to refer onwards. We aimed to establish a reproducible GP-staffed MSK and sport and exercise medicine (SEM) clinic within primary care, in keeping with recent policy changes within the UK health system. METH...

Multi-carrier code division multiple access (MC-CDMA) is modulation method for high speed data communication. The usage of MIMO MCCDMA can significantly improve the performance of wireless communication system. This paper presents the analysis of Multi Input Multi Output MultiCarrier CDMA system performance for BPSK, QPSK, MSK modulation over AWGN channel and Rayleigh channel. This represents t...

Nuclear import is an essential step in small nuclear ribonucleoprotein (snRNP) biogenesis. Snurportin1 (SPN1), the import adaptor, binds to trimethylguanosine (TMG) caps on spliceosomal small nuclear RNAs. Previous studies indicated that vertebrate snRNP import requires importin-β, the transport receptor that binds directly to SPN1. We identify CG42303/snup as the Drosophila orthologue of human...

This report presents a brief overview of the GMSK modulation scheme. 1 What is GMSK ? GMSK stands for Gaussian Minimum Shift Keying. This is a modulation scheme in which the phase of the carrier is instantaneously varied by the \modulating" signal (i.e. the information to transmit). GMSK diiers from MSK (Minimum Shift Keying) in that a Gaussian Filter of an appropriate bandwidth (deened by the ...

Identity based encryption (IBE) has received great attention since Boneh and Franklin’s breakthrough work on bilinear group based IBE [4]. Till now, many IBE schemes relying on bilinear groups with different properties have been proposed [5, 25, 29, 14]. However, one part of the user’s private key in all these IBE schemes is constructed as y = f(msk), where msk is the master key and y is an ele...

OBJECTIVES Our aim was to evaluate the quality of published guidelines on musculoskeletal ultrasound (MSK-US) for adults. METHODS Between June and July 2016, we conducted an online search for MSK-US guidelines, which were evaluated by four independent readers blinded to each other using the AGREE II tool. A fifth independent reviewer calculated scores per each domain and agreement between rev...

The main objective of this paper is to investigate the performance trade off with MSK, BPSK and QAM_64 modulation techniques. Investigations have been reported to compare the performance and tradeoffs of MSK, BPSK and QAM_64 modulation schemes. Here modulation schemes have been identified which gives significant performance improvement over the other based on energy consumption and power recept...
