Abstract

This paper proposes a low complexity precoding algorithm based on the
recently proposed Generalized Least Square Error (GLSE) scheme with generic
penalty and support. The algorithm iteratively constructs the transmit vector
via Approximate Message Passing (AMP). Using the asymptotic decoupling property
of GLSE precoders, we derive closed form fixed point equations to tune the
parameters in the proposed algorithm for a general set of instantaneous signal
constraints. The tuning strategy is then utilized to construct transmit vectors
with restricted peak-to-average power ratios and to efficiently select a subset
of transmit antennas. The numerical investigations show that the proposed
algorithm tracks the large-system performance of GLSE precoders even for a
moderate number of antennas.
