Abstract: The present application discloses a method for operating a wireless communication system. The method includes receiving a series of input data bits in a current timeslot by a transmitter and encoding the input data bits with a cross-Gray coding scheme to obtain coded information bits. Additionally, the method includes mapping the coded information bits to obtain respective multiple transmission symbols Xt for the current timeslot in a constellation diagram. Furthermore, the method includes converting the multiple transmission symbols Xt to generate a space-time matrix St of the current timeslot by incorporating spatial bits associated with orders of respective transmitting antennas based on a space-time matrix St-1 of a previous timeslot. Moreover, the method includes transmitting a respective one of elements in the space-time matrix St using a respective one transmitting antenna activated in the transmitter.
