Abstract

This paper proposes the class of Generalized Least-Square-Error (GLSE)
precoders for multiuser massive MIMO systems. For a generic transmit
constellation, GLSE precoders minimize the interference at user terminals
assuring that given constraints on the transmit signals are satisfied. The
general form of these precoders enables us to impose multiple restrictions at
the transmit signal such as limited peak power and restricted number of active
transmit antennas. Invoking the replica method from statistical mechanics, we
study the performance of GLSE precoders in the large-system limit. We show that
the output symbols of these precoders are identically distributed and their
statistics are described with an equivalent scalar GLSE precoder. Using the
asymptotic results, we further address some applications of the GLSE precoders;
namely forming transmit signals over a restricted alphabet and transmit antenna
selection. Our investigations demonstrate that a computationally efficient GLSE
precoder requires 41% fewer active transmit antennas than conventional
selection protocols in order to achieve a desired level of input-output
distortion.
