REDUCING ELECTROMAGNETIC RADIATION EMITTED FROM HIGH-SPEED INTERCONNECTS

摘要

Systems and methods reduce electromagnetic interference from high speed data carried by wired interconnects with a radio receiver for at least one protected radio frequency band. A spectral encoder changes the encoding of the high speed data to modify its frequency spectrum and reduce its spectral in the protected frequency band. The wired interconnect carries the spectrally encoded data to its destination, where it is spectrally decoded back to its original form. Spectral encoding may include polynomial scrambling. The data may be encoded with different coding parameters in parallel and the best result selected for communication over the wired interconnect. The coding parameters may be changed depending on which radio receivers and/or protected frequency bands are in use at any given time.

1. A method for reducing electromagnetic interference in a radio receiver while transmitting high-speed data over a wired interconnect, comprising:
selecting a first protected frequency band, the protected frequency band being a radio frequency range where reduced interference is desired; forwarding the high-speed data to a spectral encoder, the high-speed data having a first energy spectrum; in the spectral encoder, spectrally encoding the high-speed data to obtain encoded data with a second energy spectrum, with reduced energy in the first protected frequency band; and transmitting the encoded data over a wired interconnect.
