Space-doppler Parameter Estimation for Space-time-doppler Reception in Time-varying Multipath Ds-cdma Systems
نویسندگان
چکیده
In this paper we propose a joint space-Doppler parameter estimation algorithm for fast-fading multipath DS-CDMA communication systems. The Doppler shifts induced by the relative motion between the transmitter and the receiver, together with the associated direction-of-arrival (DOA), are jointly estimated by a semi-blind subspace-type method. The Doppler effect is successfully eliminated by a space-time-Doppler receiver after the directional and Doppler parameters are estimated.

Blind Adaptive Space-Time Receiving and Transmitting Diversities For Multiuser DS-CDMA Systems
Blind adaptive space-time processing techniques are developed for both uplink reception and downlink transmission in multiuser TDD DS-CDMA systems to overcome multipath fading effect and multiple access interference. The system consists of a spacetime array, a decorrelator, and a weight-adapter. For uplink reception, a hybrid combination of constant modulus algorithm and decisiondirected algori...
متن کاملDiffused Channel Framework for Blind Space-time Ds-cdma Receiver
In this paper, a blind space-time receiver is proposed to handle point and diffused sources for asynchronous multipath DS-CDMA systems. The receiver is based on a computationally efficient subspace-type algorithm for its joint space-time channel estimation which is insusceptible to near-far problems. The coherency between the sources is removed by a novel temporal smoothing technique operating ...

SUMMARY This paper proposes two space-time joint channel parameter estimation and signal detection algorithms for downlink DS-CDMA systems with multiple-input-multiple-output (MIMO) wireless multipath fading channels. The proposed algorithms initially use the space-time MUSIC to estimate the DOA-delays of the multipath channel. Based on these estimated DOA-delays, a space-time channel decoupler...

The mobile wireless channel o ers inherent diversity by virtue of multipath and Doppler shifts. Multipath diversity is exploited via spread-spectrum signaling employed in code division multiple access (CDMA) systems. However, the RAKE receiver commonly used in CDMA systems exploits only multipath diversity, and consequently su ers from signi cant performance degradation under fast fading. We de...
متن کاملDecentralized multiuser detection for time-varying multipath channels
Multiple-access interference (MAI) and time-varying multipath effects are the two most significant factors limiting the performance of code-division multiple-access (CDMA) systems. While multipath effects are exploited in existing CDMA systems to combat fading, they are often considered a nuisance to MAI suppression. We propose an integrated framework based on canonical multipath-Doppler coordi...
