Characterization of multi-antenna systems in RIMP and random-LOS environments using probability of detection of different bit streams

In this paper, we present characterizations of multi-antenna systems in two opposite edge environments, i.e., rich isotropic multipath (RIMP) and random line-of-sight (LOS) environments. We use the detection probability of the single or multiple bit streams (for diversity and multiplexing cases, respectively) over an ensemble of users as the characterizing quantity. The relationship between the detection probability and the throughput in RIMP is given. An wideband compact multi-port antenna is used as an example to show characterizations in both RIMP and random-LOS environment.
