An electromagnetic pulse (EMP) resistant telecommunications (telecom) system includes core components mounted within and shielded by a Faraday cage. The components include a data source or storage device. An ethernet switch selectively connects the data source or storage device to a primary satellite router and a post-EMP satellite router. Telecom signals are output from and input to the core components via low noise blocks (LNBs) and block upconverters (BUCs). A method of resisting EMP interference for a telecommunications system includes the steps of enclosing and shielding core components in a Faraday cage and providing output via LNBs and BUCs to an antenna subsystem. The antenna subsystem can include one or more antenna elements with configurations chosen from the group comprising: parabolic dish; array; unidirectional; and omnidirectional. The EMP-resistant telecom can optionally be combined with a signal regenerating subsystem and used with a signal regenerating method.

A device includes a primary sector and secondary sectors communicatively coupled to the primary sector. The processor included in the primary sector is configured to down convert a Radio Frequency (RF) signals with a first frequency to an analog baseband (IQ) signal with a second frequency, and receive a second digital baseband signal that comprises a first digital baseband signal and a digital echo signal. The first digital baseband signal comprises a training sequence signal. Further, the processor estimates a plurality of filter taps of the FIR filter based on the digital echo signal and estimate the digital echo signal in the received second digital baseband signal based on the first digital baseband signal and the plurality of filter taps of the FIR filter. The estimated digital echo signal is removed from at least one current digital baseband signal based on the down conversion of the RF signals.

This application discloses a link switching method in sidelink communication and an apparatus, to improve SL communication quality. The method may be implemented by using the following steps: A first communication apparatus communicates with a second communication apparatus through a first relay apparatus, where a link between the first communication apparatus and the first relay apparatus is a first source communication link, and a link between the second communication apparatus and the first relay apparatus is a second source communication link; the first communication apparatus establishes a destination communication link when a specified condition is satisfied; and the first communication apparatus communicates with the second communication apparatus through the destination communication link. When either or both of the two communication apparatuses moves/move, quality of the link between the two communication apparatuses may deteriorate. In embodiments of this application, communication quality between two terminals is improved through link switching.
