This paper studies the relationship between spatial and temporal entities of the space-time processing (STP) for multiple-input multiple-output (MIMO) wireless communications in a frequency-selective fading channel. Analysis based on the zero-forcing criterion suggests that minimum number of the spatial receive antenna, N, and the temporal equaliser tap, (K+1) of the `beamformer-equaliser' can be...
This paper is concerned with the use of multi-platform agent-based emitter geolocation. Multiple, self-aware, agents representing different types of emitter location method, naturally form clusters, which are controlled by the network connectivity. Each cluster provides a fusion hierarchy: each agent is able to geolocate individually, a cluster of agents can refine the emitter position using fusion...
This paper considers the use of the Hough transform image processing method applied to the problem of agent-based multi-platform, multi-sensor emitter geolocation. In this paper, improved geolocation is obtained through the fusion of three different types of measurement: angle of arrival, time difference of arrival and frequency difference of arrival. One of the main aims of this paper is to introduce...
This paper describes a novel source localization algorithm based on the Hough transform that allows different types of sensor data, such as angle of arrival and time difference of arrival data to be fused together by means of a transformation into a consistent parameterized space. A particular advantage of this method is that terrain data can also be fused with the various types of sensor data to...
