The influence of multiple outdoor interferers on in-building DS-CDMA wireless system performance

This paper examines the influence of multiple outdoor interferers on the performance of a single-floor in-building DS-CDMA wireless system. Signal correlation is identified as a key propagation parameter that can be related to wireless system performance and therefore the optimal base station location chosen when deploying the in-building system. Using measured mean path loss data integrated into a Monte Carlo analysis, it is shown that the presence of multiple outdoor interferers can significantly influence in-building system performance. If there is dominant interference emanating from one side of the building, it is desirable to place an in-building base station on the same side of the building to ensure optimal system performance. However, if there are similar levels of interference emanating from opposite sides of the building, there is not a clear best strategy that can be used to choose the optimal location of the in-building base station.
