Optimal precoding for orthogonalized spatial multiplexing in closed-loop MIMO systems
In this paper, we propose a new precoding algorithm for orthogonalized spatial multiplexing (OSM) systems over flatfading multiple-input multiple-output (MIMO) channels. The OSM sc...

On the performance of concatenated convolutional code and Alamouti space-time code with noisy channel estimates and finite-depth
Abstract--In this paper, performance of the Alamouti spacetime code (STC) [1] and performance of the concatenation between the convolutional code and the Alamouti STC are derived. ...
