Short Description

TD-SCDMA is a 3GPP standard that combines an advanced TDMA/TDD system with an adaptive CDMA component operating in a synchronous mode. Its TDD nature allows to master asymmetric services more efficiently than other 3G standards. Up- and downlink resources are flexibly assigned according to traffic needs, which is helpful in an environment with increasing data traffic, which tends to be asymmetric (mobile Internet).

TD-SCDMA invests a considerable portion of the available bandwidth is pilot symbols, midamples and guard periods. Such information has to be fully and efficiently utilized to obtain -as perfect as possible- channel knowledge. In this thesis, channel estimation techniques shall be investigated focusing on their performance-complexity tradeoff and their impact on successive operations. Therefore, Matlab blocks have to be implemented and integrated within our TD-SCDMA simulation chain, followed by implementation in VHDL code, synthesis and design optimization.
