Enhancing Wideband Multiuser MIMO Uplink Using Superimposed Pilots: Joint Receiver Design

Superimposed pilot (SIP) significantly relaxes the excessive burden of pilot overhead especially in massive multiple-input multiple-output (MIMO) systems, thus improving the spectral efficiency. In SIP-assisted systems, it is a challenging task to decouple the data and pilot which are superimposed i...
