CDMAmultiple access interferencenear-far effectIn this paper the basic methods for reducing Multiple Access Interference (MAI) and combating the near-far effect in Direct-Sequence Code-Division Multiple-Access (DS-CDMA) mobile communication systems are presented. MAI and the near-far effect are ...
In the applications, there are many problems, such as timing synchronization, near- far effect, and geometric dilution of precision.───在应用中,常常会遇到时间同步、远近效应、几何精度衰减因子等问题。 英语使用场景 near the back nearness in distance or time ...
In this paper we are going to estimate the sum capacity of a binary CDMA system in presence of the near-far effect. We model the near-far effect as a random variable that is multiplied by the users binary data before entering the noisy channel. We will find a lower bound and a conject...
aSo far, the effect of silicate pretreatment, post-sealing and additives on the corrosion resistance of phosphate coatings on HDG steel has not been documented yet. 到目前为止,硅酸盐预处理、岗位海豹捕猎和添加剂的作用在磷酸盐涂层耐腐蚀性在HDG钢未被提供。[translate] ...
and a billion in thirty years. This goes far beyond Moore’s law (the shrinking of transistors on an integrated circuit, allowing us to double the price-performance of electronics each year). Electronics is just one example of many. As another example, it took us 14 years to sequence HIV...
Families of 2D arrays can be constructed where each array has perfect autocorrelation, and the cross-correlation between any pair of family members is optimally low. We exploit equivalent Hadamard matrices to construct many families of p p × p arr
In contrast to our expectations, DTT had little effect on the absorption spectra of the 15E PCB of either UG1 or 2 (data not shown). However, when βME, which is smaller than DTT, was added to wild-type green-absorbing UGs in the dark, the absorbance following green illumination ...
Given the fact iPhone is a far larger revenue generator than iPad, the downgrade warrants attention. As JMP notes, the market is not in a forgiving mood when it comes to missing estimates. They are highlighting $300 level as possible support for the stock which serves to create some anxiety...
As it stands, Apple is expected to introduce the second-generation iPad in three variants and several different capacities. In addition to WiFi and GSM-based models targeted at AT&T and a broad range of European 3G providers, a CDMA version catering to Verizon and some Far Ea...
