A hybrid space-time and collaborative coding scheme for wireless communications

The paper addresses space-time coding techniques for broadband wireless communications. A brief overview of the space-time block coding and collaborative coding multiple access (CCMA) techniques is presented. A new coding scheme which combines the CCMA and space-time block coding techniques is proposed. The new coding technique with transmit diversity is simulated. Results are presented, which show that the hybrid coding technique is advantageous over the space-time block coding and CCMA techniques.
