This comparative study examines the morphosyntactic parameters governing the distribution of ‘special inflection’ in constituent interrogatives and focus constructions in Hausa and Coptic Egyptian. In these languages, ‘relative’ tense-aspect-mood (TAM) markers occur in relative clauses, constituent interrogatives and declarative focus constructions. However, special inflection is not a clause-typing...
The copy theory based mixed on the traditional SLM scheme,this paper proposes a new kind of mimo-ofdm system reduces the SLM PAPR algorithm and presents the corresponding policy results. According to the simulation results, we can see this improved technique not only keeps the former probability scheme's advantages, but also further reduces the probability of high PAPR value.
This paper reviews the essence of the Walsh and Bridge functions from the point of view of the recursive relationship; it also unifies their expressions. A new kind of function—the hybrid Bridge function—is constructed from the definition of the hybrid matrix, in which the row vectors are taken from the Walsh and Bridge function matrices. We also propose a new approach for generating function sequences;...
Similarly, compared with other multi carrier modulate systems, MIMO-OFDM, also adopting this kind of technique, tends to produce high peak-to-average power ratio(PAPR), which will result in frequency spectrum spread and in-band distortion enormously due to the nonlinearity of the high power amplifier. Although the probability of high PAPR appearance is small, removing high PAPR value definitely influences...
Although mobile communication technology in our country has experienced a rapid development, surfing the Internet wirelessly supported by the current technology of GPRS and cdma2000 has come true, mobile communication lags behind in our country and still can not meet the peoplepsilas needs that they need the higher data transmission in many multimedia operations. Therefore, many scholars in our country...
