Two Models for Noisy Feedback in MIMO Channels
Vaneet Aggarwal, Gajanana Krishna, Srikrishna Bhashyam +1
Two distinct models of feedback, suited for FDD (Frequency Division Duplex) and TDD (Frequency Division Duplex) systems respectively, have been widely studied in the literature. In…

Diversity Order Gain with Noisy Feedback in Multiple Access Channels
Vaneet Aggarwal, Ashutosh Sabharwal
In this paper, we study the effect of feedback channel noise on the diversity-multiplexing tradeoff in multiuser MIMO systems using quantized feedback, where each user has m transm…
