FDD massive MIMO downlink channel estimation via selective sparse coding over AOA/AOD cluster dictionaries
(Institute of Electrical and Electronics Engineers Inc., 2018)
Sparse coding over a redundant dictionary has recently been used as a framework for downlink channel estimation in frequency division duplex massive multiple-input multiple-output antenna systems. This usage allows for ...
Iterative tap pursuit for channel shortening equalizer design
(Institute of Electrical and Electronics Engineers Inc., 2018)
In this work, an iterative tap pursuit algorithm for designing channel shortening equalizers is proposed. Similar to pursuit algorithms, a residual vector is initialized with a desired target impulse response, which is ...
