Title: Data compression and reconstruction
Inventor: PARKES STEPHEN MAXWELL
IPC: G01S13/90
Filed: 1993-05-28
Abstract: A data compression method and apparatus using Uniform Adaptive Magnitude (UPAM) coding for reducing the volume of raw data produced by a Synthetic Aperture Radar (SAR) or other radar instrument are described. The digital in-phase and quadrature (I and Q) signal samples from the SAR receiver are grouped into blocks. Each block is compressed by quantizing (32) the phase of each complex sample in the block and by accumulating (34) a measure of the average magnitude of the samples in a block. The quantized phase values and the average sample magnitude form the code for the block of raw SAR samples. The compressed raw SAR data is decompressed block by block Fig. 3, (not shown). A phase look-up table is used to translate quantized phase values into normalised I and Q values for each sample in a block. These I and Q samples are then multiplied by the average sample magnitude for the block.

Title: Disconnecting an established communication connection in a mobile radio system
Inventor: BERGENLID LARS HERBERT
IPC: H04W76/06
Filed: 1994-01-24
Abstract: A method of forcibly disconnecting a communications connection established between a mobile station MS and a mobile services switching network MSC, depending on whether the communications connection (TCHk) initially allocated to the mobile station has deteriorated or that a call connection or a handover attempt has failed. According to the proposed method, with the intention of forcing the mobile station MS to relinquish the allocated channel the network transmits to the mobile station a signal (SB1) which activates a time monitoring process in the mobile station MS, which therewith sends an acknowledgement signal (SB2) back to the network. When the network MSC does not wish the mobile station MS to retain the allocated channel (TCHk), a signal (SB3) which would stop the time monitoring process is not sent to the mobile station, therewith resulting in the release of the communications channel. Also described is a mobile station which includes counter-circuits (201, 202) for effecting the time monitoring process. <IMAGE>
