Journal ArticleDOI
Optimized signaling for MIMO interference systems with feedback
Sigen Ye,Rick S. Blum +1 more
TL;DR: This work model the system as a noncooperative game and perform iterative water-filling to find the Nash equilibrium distributively and proposes several numerical approaches to decide the covariance matrices of the transmitted signals and compare their performance in terms of the system mutual information.
Journal ArticleDOI
Adaptive OFDM Systems With Imperfect Channel State Information
TL;DR: It is shown that multiple estimates from different frequencies or times can enhance the performance significantly, which enables the adaptive OFDM system to tolerate larger errors in channel estimation or longer delay in CSI.
Proceedings ArticleDOI
Adaptive modulation for variable-rate OFDM systems with imperfect channel information
TL;DR: The use of multiple estimates is shown to mitigate the effect of CSI delay, and robust approaches are proposed that are less sensitive to CSI errors.
Proceedings ArticleDOI
Optimum signaling for MIMO-OFDM systems with interference
Sigen Ye,Rick S. Blum +1 more
TL;DR: Numerical results show that using the optimum approach for cases without interference does not always achieve system capacity, and the overall system performance is improved by forcing users to use different subcarriers or to transmit using less antennas or both.
