This paper describes a low-complexity generic receiver for burst-mode continuous phase modulation. The burst consists of a continuous wave (CW) signal followed by a pseudorandom sequence and a data sequence modulated by continuous phase modulation (CPM). Joint coarse carrier frequency, phase and time synchronization is performed on the CW signal. Fine time synchronization is performed on the ps...
Performance Enhancement of Continuous-Phase Modulation Based OFDM Systems Using Chaotic Interleaving
In this paper, we propose a chaotic interleaving scheme for continuous-phase modulation based orthogonal frequency-division multiplexing (CPM-OFDM) systems. The idea of chaotic maps randomization (CMR) is exploited in this scheme. CMR generates permuted sequences from the sequences to be transmitted with lower correlation among their samples, and hence a better bit error rate (BER) performance ...
Eisai hyperbilirubinemic mutant rats (EHBRs) with conjugated hyperbilirubinemia were recently derived from Sprague-Dawley rats (SDRs). The pharmacokinetic characteristics of the beta-lactam antibiotic cefpiramide (CPM), which is mainly excreted into bile, were investigated in 10- and 20-week-old EHBRs and were compared with those in 20-week-old healthy SDRs. The pharmacokinetic parameters of CP...
Electrogastrograms (EGGs) were recorded in patients both before and after receiving proximal gastrectomy plus jejunal interposition (PGJI) or just after receiving total gastrectomy plus jejunal interposition (TGJI). Intraluminal pressure was also recorded in some postoperative patients. The EGG 3 cpm component (2.5-4.9 cpm) remained after PGJI, but subsequently decreased with a significant redu...
Electrogastrograms (EGGs), heart and respiratory rates were recorded simultaneously from human subjects and analyzed spectrally by the maximal entropy method. The stress of the mirror drawing test (MDT) significantly increased both the heart and respiratory rates with an associated increase in LF/HF ratios. MDT stress, however, increased (excited groups) or decreased (inhibited groups) the powe...
در این رساله ویژگیهای ادبی دو کتاب تاریخ بیهقی و تاریخ جهانگشای جوینی مورد بررسی و تطبیق قرار گرفته است. نخست براساس منابع مختلف تعاریفی از سبک ارائه شده و سپس در دو فصل جداگانه ویژگیهای سبکی این دو اثر از کوچکترین جز زبانی (صوت و واج) تا بزرگترین جز آن یعنی جمله مورد بررسی قرار گرفته و برای هر کدام از این انواع مثالهایی ایراد شده است. در فصلهای سوم و چهارم صناعات ادبی این دو کتاب مد نظر قرار گ...
The pin-based pointwise energy slowing-down method (PSM) has been refined through eliminating the approximation for using pre-tabulated collision probability during calculation. A table is generated by assuming that material composition and temperature are constant in fuel pellet (CPM). Refined PSM (PSM-CPM), which calculates isolated calculation CPM, can consider nonuniform distribution. For m...
Mixed states are of interest in quantum mechanics for modelling partial information. More recently categorical approaches to linguistics have also exploited the idea of mixed states to describe ambiguity and hyponym / hypernym relationships. In both these application areas the category Rel of sets and binary relations is often used as an alternative model. Selinger’s CPM construction provides t...
Age-Dependent Decline of Endogenous Pain Control: Exploring the Effect of Expectation and Depression
Although chronic pain affects all age ranges, it is particularly common in the elderly. One potential explanation for the high prevalence of chronic pain in the older population is impaired functioning of the descending pain inhibitory system which can be studied in humans using conditioned pain modulation (CPM) paradigms. In this study we investigated (i) the influence of age on CPM and (ii) t...
The long flexuous virions of the Closteroviridae have a unique bipolar architecture incorporating two coat proteins, with most of the helical nucleocapsid encapsidated by the major coat protein (CP) and a small portion of one end encapsidated by the minor coat protein (CPm). It is not known whether CPm encapsidates the genomic RNA and, if so, which end and what effects transition between the tw...
