Latest Patents
Among his latest innovations, Ottersten's patents focus on "Channel assignment and call admission control for spatial division." These methods are specifically tailored for Spatial Division Multiple Access (SDMA) systems. His patents introduce three sophisticated methods for uplink channel assignment: the cost function method, predictive method, and hierarchical method. The cost function method calculates a cost based on a weighted correlation matrix of spatial signatures from active subscribers. The predictive method forecasts uplink power and interference for each channel, selecting the one with the minimal interference or maximum Signal-to-Interference-plus-Noise Ratio (SINR). Lastly, the hierarchical method effectively combines elements from both the cost function and predictive methods. Ottersten's inventions also encompass downlink channel assignment and call admission control, contributing to the development of spectrally efficient, high-capacity wireless communication systems.
