  Multiple-input multiple-output (MIMO) systems find immense potential and
applicability in the long term evolution (LTE), 5G, Internet of Things (IoT),
vehicular ad hoc networks (VANETs), and tactical communication systems. Jamming
poses significant communication hindrance as well as security risks to the
wireless communication systems. The achievable rate and reliability are the two
most compromised aspects of a wireless link under such severe jamming. Owing to
the high capacity and reliability of MIMO systems, they are increasingly used
in tactical and critical applications. Therefore, it becomes essential to
assess and enhance their sustenance under hostile jamming scenarios. To this
end, we address the rate and reliability requirements of a MIMO OFDM system and
propose a novel rate-reliability beamformer transceiver design for highly
reliable and spectrally efficient operation under the most detrimental jamming
attacks. We consider the disguised all band and multiband jamming where the
jammer continuously attempts to mimic the legit transmissions. Additionally, we
evaluate the rate and reliability performance under barrage jamming.
  The significant contributions of the proposed rate-reliability beamformer
scheme are: (i) achieves a minimum of 2 orders of magnitude better reliability
in contrast to the state-of-the-art, (ii) outperforms the state-of-the-art
scheme by 1.4x with regards to achievable spectral efficiency, (iii) a very low
complexity (O(|Q|)) decoder is presented, and (iv) first work to evaluate the
performance of state-of-the-art transmit diversity scheme under hostile jamming
attacks.
