Frequency selective fading channel estimation in OFDM systems using KL expansion
(2005)
This paper proposes a computationally efficient linear minimum mean square error (MMSE) channel estimation algorithm based on KL series expansion for OFDM systems. Based on such expansion no matrix inversion is required ...
Pilot-aided bayesian MMSE channel estimation for OFDM systems: Algorithm and performance analysis
(2004)
This paper proposes a computationally efficient pilot-aided minimum mean square error (MMSE) channel estimation algorithm for OFDM systems. The proposed approach employs a convenient representation of the discrete multipath ...
Blind phase noise estimation and data detection based on SMC technique and unscented filtering
(2006)
In this paper, a computationally efficient algorithm is presented for tracing phase noise with linear drift and blind data detection jointly, based on a sequential Monte Carlo(SMC) method. Tracing of phase noise is achieved ...
Effect of channel estimation errors on the performance of space time coded systems with antenna selection
(2007)
This paper presents the effects of channel estimation errors on the performance, especially diversity gain, of space-time coded systems with antenna selection. We consider maximum signal to noise ratio as the antenna ...
İterative receiver for DS-CDMA systems in the presence of time-varying channels
(2008)
In this paper, we present an efficient iterative receiver structure of tractable complexity for joint multiuser detection and multichannel estimation (JDE) ofdirect-sequence code-division multiple-access systems operating ...
