“…A desired transmission and an interfering transmission will have a high correlation if they undergo similar variations due to distance-dependence and shadowing. This phenomenon is commonly known as correlated shadowing [1][2][3] and occurs when both the desired and interfering transmissions share similar propagation paths and therefore encounter similar obstacles during propagation. In a system with correlated shadowing (i.e.…”

“…It is known that signal correlation levels between a desired transmission and one or more interfering transmissions can have significant implications on in-building system performance and deployment [1][2][3][4]. Butterworth et al [1][2] showed that in the absence of outdoor interference, deploying in-building base stations to yield high levels of signal correlation (vertically aligned base stations) provides significantly better system performance than if there are negative correlations (offset base stations).…”

“…Butterworth et al [1][2] showed that in the absence of outdoor interference, deploying in-building base stations to yield high levels of signal correlation (vertically aligned base stations) provides significantly better system performance than if there are negative correlations (offset base stations). The influence of a single outdoor interferer on the performance of in-building systems is considered in [3]. If an in-building base station is placed so that its transmission is positively correlated with the outdoor interferer's transmission, up to ten times better system performance is achieved than if the transmissions are negatively correlated.…”

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.

Using indoor propagation measurements, an investigation of the influence of antenna directivity on the performance of an indoor wireless system is presented. By comparing the path loss data measured from collocated omnidirectional and directional antennas (at different orientations), it is shown that the 'effective' directivity of a directional antenna is heavily dependent on the surrounding environment. Antenna directivity and orientation are shown to influence the level of interference within a system and, therefore, affect overall system performance. Analysis of a simple indoor system with two cochannel base stations showed that the use of directional antennas could either enhance or degrade system performance, relative to a system using omnidirectional antennas. In the best case the use of directional antennas decreased outage probability by 56%, while in the worst case the outage probability increased by 66%.
