A recursive link adaptation algorithm for MIMO systems

An algorithm to adjust the coding modulation (CM) scheme in a multiple-input multiple-output (MIMO) wireless communication system is proposed and analyzed. The CM scheme selected for each transmitter is determined by a recursive procedure at the receiver, taking into account estimated signal to noise ratio and the properties of available CM schemes. The performance of the algorithm was tested using pseudo-inverse (PINV) detection algorithm supporting constant BER criteria.
