  The practical utilization of the symbol-level precoding in MIMO systems is
challenging since the implementation of the sophisticated optimization
algorithms must be done with reasonable computational resources. In the real
implementation of MIMO precoding systems, the processing time for each set of
symbols is a crucial parameter, especially in the high-throughput mode. In this
work, a symbol-level optimization algorithm with reduced complexity is devised.
Performance of a symbol-level precoder is shown to improve in terms of the
processing times per set of symbols.
