The out band spurious spectrum is limited by raised cosine filter in transmitter, and the shadow effect can be removed by combining the signal power of two branches in receiver.

Taking account of the up-conversion and cross-relaxation effects of cooperation, the spectrum analysis of highly doped EDWA can be carried out over a wider frequency band.

由于考虑了协同上转换和交叉弛豫效应，该算法能够对高掺杂的EDWA进行较宽频谱的分析。

A redshift can be measured when light from a galaxy is broken up and spread out into a band of colors called a spectrum.

当从星系发出的光被分解展开成光谱的时候就可以测出红移了。

If the bill passes, this will leave both T-Mobile and Sprint out of the 700-MHz band, but the small amount of spectrum that makes up the D Block would not have been enough to serve their customers.
