N2 - In this paper we evaluate a recently proposed multiple-input multiple-output (MIMO) system called the Layered Steered Space-Time Codes (LSSTC). The LSSTC system is evaluated for multi-user environments where scheduling can be used to increase the system capacity by harnessing the multi-user diversity. This evaluation is done by comparing the capacity and the probability of error for several combinations of algorithms and criteria for scheduling users' data. The results obtained show that many of the scheduling criteria derived in literature does not perform well with the LSSTC system. Instead, a scheduling criterion that directly coincides with the detection mechanism of the LSSTC receiver is derived. This scheduling criterion can jointly maximize the capacity and minimize the error probability. Also we derive a formula for the PDF of the maximum preprocessing SNR for a Greedy-based multi-user LSSTC.
