Abstract :
The present paper proposes a low complexity algorithm of the channel estimation for HF serial-tone MIMO communication channel, based on: 1) presentation of MIMO channel as a set of SIMO channels, 2) tracking of main vectors of eigenvalue decomposition (EVD) of the impulse response correlation function (IR) of a SIMO channel; 3) current MMSE estimation of IR with the approximation of the decreased rank of the correlation matrix IR.
