Wired CDMA Interface with Adaptivity for Interconnect Capacitances

چکیده
Wired CDMA interface with adaptivity for interconnect capacitances is designed to receive transmitted data even under a wide variety of connection topologies. The variable gain amplifier (VGA) is one of key circuit blocks to realize the adaptivity for interconnect capacitances. The system level numerical simulations derive the VGA specifications that the required VGA gain range is from 0.37 to 2.0, which can be realized easily using a multiple-differential-pair technique. key words: CMOS analog circuit, variable gain amplifier, CDMA

متن کاملAn Adaptive Blind Receiver for Asynchronous Ds-cdma Based on Recursive Svd and Rls
| In this paper we present an adaptive blind receiver for asynchronous direct sequence code division multiple access (DS-CDMA) communication over multipath channels. The algorithm can handle both multiuser interference (MUI) and intersymbol interference (ISI) by the use of a twofold spreading together with some spatial over-sampling. It is based on a blind virtual channel identiication using th...
