The effect of various channel conditions on the performance of different antenna array architectures

An extensive investigation into the effect of many different channel conditions on the performance of handset antenna arrays is studied. We concentrate our analysis on investigating the impact of angular parameters associated with mean azimuth-of-arrival (MAOA), azimuth spread (AS), mean elevation-of-arrival (MEOA) and elevation spread (ES) of the propagation channel under study. The performance analysis is done by comprehensive simulations that incorporate various channel conditions ranging from outdoor to indoor environments on three types of antenna array architectures, i.e., uniform linear array, uniform circular array and uniform rectangular array. A theoretical probability of error is also developed which shows excellent agreement with the simulation results. The importance and dependency of the above parameters on the system performance are examined. Results show that the system performance is always dependent on AS and ES while the impact of MAOA and MEOA is array dependent.
