Patent CA-2300428-A1 (CA)
Inventor: MUELLER FRANK
IPC: H04W72/04
Filed: 1998-08-25
Abstract: A method of communicating control information in systems that support multiple modulation schemes for communicating voice or data and control information. To provide backward compatibility dedicated control channels use the modulation scheme used in current systems, for example GMSK modulation scheme. Traffic channels and associated control channels use linear modulation schemes that have the same symbol rate. The modulation scheme of the associated control channel uses a reduced signal set of the modulation scheme used for traffic channels. Also, an in-band signalling procedure is used to indicate to a receiving station the modulation type, channel coding and speech coding used for a transmitted burst.

Title: Air press
Inventor: MURRY PATRICK W
IPC: D21F1/48
Filed: 1998-10-01
Abstract: An air press for dewatering a paper web according to the present invention exhibits improved performance in the forming and pressing sections of a papermaking machine. The air press comprises a pressurized box which is positioned opposite a vacuum box.

Inventor: NIEGEL MICHAEL
IPC: H04J13/00
Filed: 1999-07-19
Abstract: The present invention relates to spreading data of a plurality of digital communication channels having different data rates with code sequences having different lengths. The inventive circuit allows to use a single hardware unit for spreading communication channels having different data rates, e.g. in a CDMA telecommunications system. This is achieved by processing either a single symbol and a corresponding long code in appropriate storage means for a channel with a lowest rate or to process a plurality of symbols and corresponding shorter code sequences of communication channels having higher data rates. Thus, a joint chip rate after spreading is obtained using a single hardware structure.
