Adaptive pilot allocation for estimating sparse uplink MU-MIMO-OFDM channels

We consider uplink multiuser multiple-input multiple-output (MIMO) orthogonal frequency division multiplexing (OFDM) communication. The transmit (Tx) side of the envisaged system consists of several single-antenna users or/and several …
