EM-Based sequence estimation for wireless systems with orthogonal transmit diversity
(IEEE, 2003)
In this paper, an optimum sequence estimation algorithm for wireless systems with Alamouti's two transmitter diversity in the presence of multipath fading is proposed. The algorithm is based on a jointly iterative channel ...
Frequency selective fading channel estimation in OFDM systems using KL expansion
(IEEE, 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 ...
