In so called MIMO (multiple input multiple output) systems, multiple antennas are deployed both at the transmitter and the receiver. In MISO (multiple input single output) systems, the receiver has only one antenna, and the multiple transmit antennas are used for transmit diversity.The key aspects of multiple antenna transceiver techniques for evolving 3G systems and beyond are presented.

They consider the historical process of standardisation and its social consequences, in particular discrimination against low-status and ethnic minority groups on the basis of their language traits. 410 0$aRoutledge Linguistics Classics 606 $aCommunicative competence 606 $aEnglish language -- Standardization 606 $aLanguage and languages -- Ability testing 606 $aLanguage and languages -- Variation 606 $aStandard language 615 4$aCommunicative competence. 615 4$aEnglish language -- Standardization. 615 4$aLanguage and languages -- Ability testing. 615 4$aLanguage and languages -- Variation. 615 4$aStandard language. 676 $a420 676 $a428 700 $aMilroy$b James.$0152873 701 $aMilroy$b Lesley$0152039 801 0$bAU-PeEL 801 1$bAU-PeEL 801 2$bAU-PeEL 906 $aBOOK 912 $a9910778919703321 996 $aAuthority in language$91462221 997 $aUNINA
