Spatial multiplexing (SM) proves effective in increasing data rate in a narrowband multiple-input multiple-output (MIMO) system. Past work has shown that unitary precoding with limited feedback can be used at the transmitter to improve the bit error rate (BER) performance. Further performance gain can be achieved if power control is used along with unitary(More)
While antenna selection has been shown to be effective in improving bit error rate (BER) performance in multipleinput-multiple-output (MIMO) systems, further performance gain can be obtained by transmitting only when the channel gains are sufficiently high and by using power control to compensate for channel variations. Truncated channel inversion is an(More)
A cross-layer method is proposed for optimizing, controlling and improving the quality of video transmission over wireless networks using scalable video coding (SVC) and multiple-input multiple-output (MIMO) transmission with channel state feedback (CSI). Multiple video sub-streams are created by a content-based partitioning and sorting of the enhancement(More)
