Dirty Paper Coding for the MIMO Cognitive Radio Channel with Imperfect CSIT
Chinmay S. Vaze, Mahesh K. Varanasi
A Dirty Paper Coding (DPC) based transmission scheme for the Gaussian multiple-input multiple-output (MIMO) cognitive radio channel (CRC) is studied when there is imperfect and per…
On the Achievable Rate of the Fading Dirty Paper Channel with Imperfect CSIT
Chinmay S. Vaze, Mahesh K. Varanasi
The problem of dirty paper coding (DPC) over the (multi-antenna) fading dirty paper channel (FDPC) Y = H(X + S) + Z is considered when there is imperfect knowledge of the channel s…
Dirty Paper Coding for Fading Channels with Partial Transmitter Side Information
Chinmay S. Vaze, Mahesh K. Varanasi
The problem of Dirty Paper Coding (DPC) over the Fading Dirty Paper Channel (FDPC) Y = H(X + S)+Z, a more general version of Costa's channel, is studied for the case in which there…
Joint Beamforming for Multiaccess MIMO Systems with Finite Rate Feedback
Wei Dai, Brian C. Rider, Youjian Liu
This paper considers multiaccess multiple-input multiple-output (MIMO) systems with finite rate feedback. The goal is to understand how to efficiently employ the given finite feedb…
Optimal Constellations for the Low SNR Noncoherent MIMO Block Rayleigh Fading Channel
Shivratna Giri Srinivasan, Mahesh K. Varanasi
Reliable communication over the discrete-input/continuous-output noncoherent multiple-input multiple-output (MIMO) Rayleigh block fading channel is considered when the signal-to-no…
On the Information Rate of MIMO Systems with Finite Rate Channel State Feedback and Power On/Off Strategy
Wei Dai, Youjian Liu, Brian Rider +1
This paper quantifies the information rate of multiple-input multiple-output (MIMO) systems with finite rate channel state feedback and power on/off strategy. In power on/off strat…
