The First Order Space-Time Reed-Muller Codes

摘要

We present a family of Space-Time codes for the noncoherent MIMO channel. These space-time codes are strongly related to standard binary fist order Reed-Muller codes. In particular, their decoder can be built from several parallel decoders of first order Reed-Muller codes. We show that these codes allow transmission with rates close to the MIMO noncoherent unitary space-time codes capacity in the low signal to noise ratio (SNR) regime.
