Abstract
In this letter, we present a squaring method to simplify the decoding of or thogonal space-time block codes in a wireless system with an arbitrary numb er of transmit- and receive-antennas. Using this squaring method, a closed- form expression of signal-to-noise ratio after space-time decoding is also derived. It gives the same decoding performance as the maximum-likelihood r atio decoding while it shows much lower complexity.
