Space-time coding is a coding technique for obtaining spatial diversity over multipath fading channels using multiple transmit antennas. Recently, Liu et al. developed the Σo -rank criteria for space-time codes. It provides a sufficient condition on codeword and generator matrices defined over finite rings Z2k(j) in order to ensure full spatial diversity with 22k -QAM modulation. Here, we generalize the Σo -rank criteria and derive a sufficient condition on the generator matrices defined over finite rings Z2l(j) in order to ensure full spatial diversity with 22k -QAM modulation for any positive integer l less than or equal to k.
