Abstract

An optimized relaying method for multi-antennas
cooperative networks, estimate-and-forward (EF) strategy for
MIMO relay, is proposed and analyzed in this paper. According
to our theoretical analysis, it performs like amplify-and-forward
(AF) for the low signal noise ratio (SNR) region and behaves
like detect-and-forward (DF) for the high SNR region. For the
relay networks with a large number of antennas and/or high
order constellations, two approximate methods are proposed to
reduce the complexity of the signal estimation at the relay. The
first one uses a list sphere decoder to generate an estimate list
and to obtain the approximate minimum mean squared error
(MMSE) estimate based on the reduced list. The proposed list
EF retains the advantages of the exact EF relay strategy in large
MIMO relay networks at a negligible performance loss. The
second algorithm computes the estimate of the symbols using
Gaussian approximation to approximate the summation to be
integral. We find the proposed EF scheme performs better than
both AF and DF across all SNRs without switching algorithms
for different SNRs.
