  • Apparatus and method for jammer resistant protocol stack design
    Patent number: 11115090
    Abstract: An apparatus and method for providing a protocol stack design which resists active jammers. The apparatus including a transmitter component, the transmitter component including: a rate-2 orthogonal space-time block code (OSTBC) encoder for processing a set of information symbols to produce a set of encoded signals; a precoder module coupled to an output of the rate-2 OSTBC encoder for modifying a signal-to-jammer plus noise ratio (SJNR) of the set of encoded signals; and an eigen-beamformer module coupled to an output of the precoder module, and configured to generate a set of symbols for transmission via a set of eigenmodes of a channel covariance matrix for the transceiver.
