Abstract: The present invention relates to management of a state memory in a communications unit. The state memory then stores states that are used in message-based communication with external units in a communications system. The data message communicated between the units are defined into multiple message classes. Furthermore, the state memory is divided into multiple memory portions, where each such memory portion is assigned to store states associated with a specific message class. This will prevent overwriting important states with less useful states.

Abstract: The invention relates to environmental characterization on the basis of an Ultra Wide Band (UWB) radiofrequency communication network. Pulses are emitted and the waveform received is compared with predicted waveforms corresponding to well determined interactions between the wave and its environment. The comparison is done by searching for maximum temporal correlation. The interactions can be notably reflections of the wave on walls or obstacles. The deformations are very dependent on the nature of the materials and directions in which the pulses are emitted and received. If predicted waveforms are stored for various pairs of direction of emission and of reception, it is possible through these correlation operations to find where a wall which gave rise to a reflection is situated.
