An Iterative List-Based Multiuser Detector for Overloaded Receivers in a Rayleigh Fading Channel
We consider a wireless communication system
where multiple co-channel users transmit data via a synchronous,
frequency-flat Rayleigh fading channel. The receiver employs
an antenna array. The paper develops an iterative list multiuser
detector for overloaded applications where the number
of transmitted signals exceeds the number of receive antennas.
The receiver uses a linear preprocessor to reduce co-channel
interference followed by a multiuser detector with an iterative
groupwise symbol detection algorithm that extracts a list of
the most likely user symbols. Simulation results show that the
proposed detector provides good complexity-performance trade
