Managing Hardware Impairments in Hybrid Millimeter Wave Mimo Systems: A Dictionary Learning-Based Approach
asilomar conference on signals, systems and computers, 2019.
Compressed sensing-based strategies have been derived in prior work to reduce training overhead when estimating the high dimensional millimeter wave MIMO channel. These techniques rely on a channel model based on a sparsifying dictionary which does not account for hardware impairments such as calibration errors, mutual coupling effects, o...More
