3 results about "Linear channel" patented technology

This application belongs to the field of communication signal processing technology, and more specifically, relates to a method and system for co-channel interference cancellation based on a multi-star operation neural network. By calculating the equivalent linear channel response between the target received signal and the target transmitted signal, the target linear interference component of the target received signal can be accurately and quickly obtained. This application introduces a target nonlinear reconstruction model with multiple target single-star models, and then utilizes two feature branches for linear transformation and star operation to quickly and accurately obtain the target nonlinear interference component of the target received signal from multiple dimensions without increasing the stacking of deep convolutional layers or a large number of recurrent structures. Thus, based on the target linear interference component, the target nonlinear interference component, and the target received signal, effective cancellation of co-channel interference signals in a high-speed dynamically changing channel environment can be achieved.

A device (100) for traversing a suspended cable (110) anchored at each end, and the device comprising: an open non-linear channel (130) for receiving, by a slotting action, the suspended cable, said non-linear channel defining a minor segment (165-2); a motor (135); and a drive mechanism (140), powered by the motor, arranged within the minor segment so as to contact the suspended cable when received by the non-linear channel and thereby to drive the device along the suspended cable.
