This paper empirically investigates the performance of distributed antenna systems (DAS) based on switched diversity combining for indoor user equipment (UE) to access point (AP) communications at 60 GHz. Among the candidate pool of switched diversity combining techniques, the pure selection combining (PSC), switch-and-examine combining (SEC) and SEC with post-examining selection (SECps) schemes are utilized to combine the received composite fading signals. Unlike the PSC scheme, the performance and complexity of the SEC and SECps schemes vary according to the switching threshold that is used, highlighting the importance of the selection of an appropriate switching threshold level. Also in this study, diversity specific equations are developed under the assumption of independent and identically distributed F composite fading channels. These are then utilized to model the composite fading behavior observed at the output of each of the combiners. Over all of the measurement scenarios considered in this study, it is found that the theoretical models provided an adequate fit to the composite fading observed at the output of each of the combiners.
