The Design of a Spatial Diversity Model to Mitigate Narrowband and Broadband Interference in DSSS Ad


Abstract – Spatial diversity has been gaining significant momentum in cellular systems due to its ability to improve radio links in mobile wireless channels. Techniques of spatial diversity have been expanded to build foundations for advanced antenna array technology, to increase capacity in mobile wireless communication systems due to radiation patterns that direct energy only in the intended direction, thereby greatly reducing interference. Similar benefits may be gained in DSSS ad hoc networks, though work in this area has been limited. To exploit spatial processing in future ad hoc networks, accurate array designs that embed spatial characteristics of the channel and radiation patterns are necessary to quantify the performance benefits. Therefore, in this study we designed a spatial diversity model and using simulation examined the performance benefits attained when configured in a DSSS ad hoc network, subject to channels with narrowband and broadband interference.
