Khatri-Rao space-time codes

  title={Khatri-Rao space-time codes},
  author={Nikos D. Sidiropoulos and Ramakrishna S. Budampati},
  journal={IEEE Trans. Signal Processing},
Space-time (ST) coding techniques exploit the spatial diversity afforded by multiple transmit and receive antennas to achieve reliable transmission in scattering-rich environments. ST block codes are capable of realizing full diversity and spatial coding gains at relatively low rates; ST trellis codes can achieve better rate-diversity tradeoffs at the cost of high complexity. On the other hand, V-BLAST supports high rates but has no built-in spatial coding and does not work well with fewer… CONTINUE READING
