Apparatus and method for jammer resistant protocol stack design

A method for transmitting a signal via a transmitter component of a transceiver assembly, the method comprising:

• converting a set of information symbols into a set of corresponding orthogonal space-time block code (OSTBC) symbols;
• precoding the set of OSTBC symbols to increase a signal to jammer noise ratio (SJNR) of the OSTBC symbols;
• and
• generating, via an eigen-beamformer, the signal for transmission based on the precoded OSTBC symbols, the eigen-beamformer being configured to generate the signal via a set of eigenmodes of a channel covariance matrix for the transceiver assembly.

An adaptive transmitter, comprising:

• a forward error correction (FEC) encoder for FEC encoding a set of input bits;
• a quadrature amplitude modulation (QAM) modulator for QAM modulating an output of the FEC encoder to generate a set of information symbols;
• a rate-2 orthogonal space-time block code (OSTBC) encoder for processing the 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, the precoder module including a full-band precoder and a multi-band precoder;
• 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 transmitter.
