On the Performance of Blind Chip Rate Estimation in Multi-Rate CDMA Transmissions Using Multi-Rate Sampling in Slow Flat Fading Channels
This paper considers blind chip rate estimation of DS-SS signals in multi-rate and multi-user DS-CDMA systems over channels having slow flat Rayleigh fading plus additive white Gaussian noise. Channel impulse response is estimated by a subspace method, and then the chip rate of each signal is estimated using zero crossing of estimated differential channel impulse response. For chip rate estimat...

متن کاملBlind Delay Estimation in Multi-rate Asynchronous Ds-cdma Systems
The problem of time delay estimation in multi-rate asynchronous Direct-Sequence Code-Division-Multiple-Access systems is investigated. The nature of multi-rate traac requires the modiication of previously proposed single-rate algorithms in order to eeciently exploit the properties of the signals. Both subspace and non-parametric methods are considered for two types of multi-rate access schemes,...
متن کاملBlind channel estimation in multi-rate CDMA systems
Multi-rate CDMA is a potentially attractive multiple access method for future broad-band multimedia wireless networks that must support integrated voice/data traffic. The primary impairment for such multi-rate systems is the multipath nature of radio channels that results in intra-user inter-chip interference (ICI) and multi-user interference (MUI) between different users’ symbols. Explicit kno...
متن کاملBlind channel estimation in multi-rate multicarrier DS-CDMA systems
Multi-rate multicarrier DS-CDMA is a potentially attractive multiple access method for future broadband wireless multimedia networks that must support integrated voice/data traffic. This paper proposes a subspace based channel estimation scheme for multi-rate multicarrier DS-CDMA, which is applicable to both multicode and variable spreading factor systems. The performances of the proposed schem...
