Webb10 apr. 2024 · Multiple transmit nodes emitting the MU-MIMO-OFDM modulation signals at the same carrier frequency and one receiver collecting the target-reflected signals for target location and velocity estimation are considered. This is a typical scenario when using the fifth-generation (5G) communication network signal for target sensing. WebbMIMO systems can bring signiﬁcant multiplexing [12]– [14] and diversity gains [15], [16] in wireless communication systems. In the block-fading channel the structure of the channel and the degrees of freedom introduced by multiple antennas must be exploited in order to appropriately design the receiver. Approaches to receiver design include ...
