GDoF Region of the MISO BC: Bridging the Gap Between Finite Precision and Perfect CSIT

For the K = 2 user MISO BC, i.e., the wireless broadcast channel where a transmitter equipped with K = 2 antennas sends independent messages to K = 2 receivers each of which is equipped with a single antenna, the generalized degrees of freedom (GDoFs) region are characterized for arbitrary channel strength and channel uncertainty levels for each of the channel coefficients. The result is extended to K > 2 users under additional restrictions which include the assumption of symmetry.
