Abstract
In this letter, we derive the optimal diversity- multiplexing tradeoff for a frequency selective MIMO channel with resolution-constrained channel feedback. The additional degree of freedom provided by the channel multipaths is succinctly captured in the tradeoff characterization. For instance, in a L-path SISO channel, with K-level feedback, the maximum diversity increase is exponential in K.
