EM-Based sequence estimation for wireless systems with orthogonal transmit diversity
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 ...
A novel space-time-frequency coded system design for OFDM over fast fading channels
This work is concerned with a transmitter diversity technique for wireless communications over frequency selective fading channels. The proposed technique utilizes orthogonal frequency division multiplexing (OFDM) to ...
Channel estimation for space-time block coded OFDM systems in the presence of multipath fading
In this paper, a computationally efficient, non-data-aided maximum a posterlori(MAP) channel estimation algorithm is proposed for orthogonal frequency division multiplexing (OFDM) systems with transmitter diversity using ...
