Patent CA-2289231-C (CA)
Title: A subscriber unit and method for use in a wireless communication system
Inventor: ODENWALDER JOSEPH P
IPC: H04B1/707
Filed: 1998-05-13
Granted: 2007-07-10
Abstract: A set of individually gain adjusted subscriber channels (402, 404, 411, 415) are formed via the use of a set of orthogonal subchannel codes (Wc, Ws, Wf) having a small number of PN spreading chips per orthogonal waveform period. Data to be transmitted via one of the transmit channels is low code rate error correction encoded and sequence repeated before being modulated with one of the subchannel codes, gain adjusted, and summed with data modulated using the other subchannel codes. The resulting summed data (410, 420) is modulated using a user long code and a pseudorandom spreading code (PN code) and upconverted for transmission. The use of the short orthogonal codes provides interference suppression while still allowing extensive error correction coding and repetition for time diversity to overcome the Raleigh fading commonly experienced in terrestrial wireless systems. The set of sub-channel codes may comprise four Walsh codes, each orthogonal to the remaining codes of the set. The use of four sub-channels is preferred as it allows shorter orthogonal codes to be used, however, the use of a greater number of channels and therefore longer codes is acceptable. Preferably, pilot data is transmitted via a first one of the transmit channels and power control data transmitted via a second transmit channel. The length, or number of chips, in each channel code may be different to further reduce the peak-to-average transmit power for higher rate data transmission.

Abstract: The RF propagation of a wireless system is normalized to remove the directionality, orientation and gain characteristics of the antennae deployed in the system to allow for enhanced growth management of a wireless system. RF propagation data for a wireless system is gathered by any collection method. For example, drive test of the cellular system can be performed to receive and measure the signal strength throughout the system to determine the receive power of signals from cell sites in the system. Other methods such as uplink collection, E911 data can be used. After measurements of the system are collected, the data is past- processed to remove the effective gain achieved by each antenna associated with each of the signals to normalize the signals to a conceptual antenna having an isotropic radiation pattern. A database of the antenna gain and deployment patterns of the actual antennae in the system is used to normalize the data. The expected receive power of the conceptual antennae signals at the locations throughout the cellular system are determined using a propagation model. The modeled conceptual signals correspond to the measured signals and the characteristics of the conceptual antennae substituted to model the conceptual signals. The Propagation modeling can be revised through analysis of the correlation with the measured data. Once the system has been normalized and the propagation model is acceptably accurate, the system designer can model data corresponding to a variety of antenna gain, directionality and orientation choices to effectively enhance growth management through effective redeployment and specification of antennae without the need to physically experiment with antenna of varying characteristics and perform numerous data collections after antennae substitutions or reconfigurations. A final data collection such as a final drive test can be performed after implementation of a new antenna deployment.

Title: Method for manufacturing metal parts
Inventor: KOCHANEK WOLFGANG
IPC: B22F3/10
Filed: 2001-03-22
Granted: 2011-01-04
Abstract: The invention relates to a method for producing metal bodies by mixing metal compound particles with a binding agent and compacting them to form shaped parts, whereby the binding agent is subsequently removed and the metal compound is reduced to metal by gassing the same with a reductive gas at high temperatures. The reduction is carried out at temperatures lower than the sintering temperature of the reduced metal compound so that the formed reduced shaped bodies, while maintaining their original dimensions to a large extent, have a density less than that of the metal compound used. The metallic matrix obtained in such a manner can be subjected to a post compaction by applying mechanical forces. High-strength steel parts having very low residual porosities and a high geometric tolerance are obtained by sintering the matrix at usual sintering temperatures after compaction.
