Adobe_Acrobat_7.0_Professional_Keygen
第一步,打开Adobe_Acrobat_7.0_Pro_KeyGen.exe,将随机产生一个24位的序列号码.复制.
第二步,打开安装程序,点SETUP,在需要输入序列号的时候,将已复制的24位的序列号码,粘贴.
第三步,一路NEXT,选中通过电话激活方式.点NEXT
第四步,在随后产生的28位代码复制到Adobe_Acrobat_7.0_Pro_KeyGen.exe第二行,注意不要带空格
第5步,点Adobe_Acrobat_7.0_Pro_KeyGen.exe 产生激活代码.
第6步,将激活代码填入安装程序 OK
(The first step, open Adobe_Acrobat_7.0_Pro_KeyGen.exe, will generate a random sequence of 24 numbers. Copy. The second step, open the installer, point SETUP, enter the serial number required at the time, will have to copy the serial number 24 and paste. The third step, all the way NEXT, select activation by phone. NEXT-point fourth step, resulting in the following 28 code Adobe_Acrobat_7.0_Pro_KeyGen.exe copied to the second line, not to bring attention to step 5 spaces, points have to activate code Adobe_Acrobat_7.0_Pro_KeyGen.exe. Step 6, activation code will fill in the installation process OK)

vvvvA-Simple-Transmit-Diversity-Technique-in-wire
This paper presents a simple two-branch transmit
diversity scheme. Using two transmit antennas and one
receive antenna the scheme provides the same diversity order
as maximal-ratio receiver combining (MRRC) with one transmit
antenna, and two receive antennas
