Abstract: A method and apparatus for adaptively adjusting the power of a probe signal to be transmitted by user equipment based on a characteristic of received signals and system constants so as to increase the likelihood that the probe signal will be detected by system equipment of a communication system. The Doppler shift of a received pilot signal is derived and an adjustment parameter is calculated based on the Doppler shift, time interval between successive probe transmissions, and system constants. The adjustment parameter is applied to the probe signal to be transmitted to compensate for the effects of fading to be experienced by the probe signal to be transmitted.
Abstract: A modularly designed EMI shielded enclosure made from two end sections coupled to each other by crossing members. Panels and/or doors which are attached to the end sections and crossing members form seams at the points of attachment where said seams are made from overlapping surfaces which substantially reduce the amount of electromagnetic radiation leaking from the enclosure.
