Patent CA-2267714-A1 (CA)
Inventor: RUCKI JOHN STANLEY
IPC: H04B1/38
Filed: 1999-03-24
Abstract: A communication system reduces the transmitter overloading of a transmit scanning receiver by reducing transmitter signals transmitted from an overloading transmitter and received by the transmit scanning receiver. A sample of a transmitter signal to be transmitted is obtained from the transmitter before transmission.  After the transmitter signal is transmitted and received by the transmit scanning receiver, the sample is used to reduce the transmitter signal at the transmit scanning receiver. To do so, the sample is delayed, adjusted and combined with the transmitter signal. In certain embodiments, a portion of a transmitter signal is obtained from a transmit path of a transmitter prior to transmission and put on a coupled path. The transmitter signal on the coupled path is adjusted and injected into a transmit scanning path of the transmit scanning receiver to combine with a transmitter signal which was transmitted by the transmitter and received at the transmit scanning receiver. A delay element in the coupled path is used to adjust the delay on the coupled path to correspond to the delay experienced by the transmitter signal which was transmitted by the transmitter and then received by the transmit scanning receiver. Amplitude and phase adjusters on the coupled path amplitude and phase adjust the transmitter signal on the coupled path to reduce the transmitter signal on the transmit scanning path. To improve the reduction of the transmitter signal on the transmit scanning path, measurements of at least the transmitter signal on the transmit scanning path can be made, and the measurements can be used to adjust the phase and/or amplitude of the transmitter signals on the coupled path to reduce the level of the transmitter signal on the transmit scanning path. Furthermore, successive cancellation stages comprising parallel coupled paths can be implemented to provide more suppression of the transmitter signal on the transmit scanning path.

Patent CA-2280377-A1 (CA)
Inventor: MA ZHENGXIANG
IPC: H04J13/00
Filed: 1999-08-17
Abstract: A single-ended homodyne receiver demodulates quadrature signals containing spectral nulls by using an extremely low intermediate-frequency that normally would create substantial self-interference. This is accomplished by judiciously placing the spectral nulls over the critical sections of the signal spectrum, ensuring that the self-interference is minimized. As an example, a direct-sequence CDMA signal that was constructed with not more than one half the available Walsh functions is demodulated directly by placing the intermediate frequency such that spectral nulls in the CDMA signal overlap the spectral peaks in the desired signal, thereby eliminating the self-interference. This single-ended homodyne receiver can be implemented using either integrated or discrete components.

Abstract: The invention proposes an inclination control system for a rail-mounted vehicle which is negotiating a curve in the track, and in which there is a memory (3) in which the section data (S) from the track system such as for example straight sections, curves of constant radius, points and elevated sections are stored as a function of distance and/or geodetically. As a function of the constantly acquired current location of the vehicle (1), so inclination signals (N) for positioning elements (9) which serve to control inclination can be derived from these section data (S).   Advantageously, the inclination technology of the rail-mounted vehicle may so enjoy optimum and in particular precise use that always the maximum speed of the vehicle can be attained while utilising and maintaining maximum transverse acceleration.  The positioning elements for controlling the inclination are always operated without delay and with the optimum inclination signals
