Abstract :
The space-time block coding (STBC), as an important member of the space-time coding family, has been developed to take advantage of the substantial capacity increases which are available in MIMO wireless systems. After the introduction of space-time coding, the channel model of the MIMO is presented for STBC. Then the encoding and decoding algorithm under a QAM constellation for STBC are introduced. Finally, the simulation results for various STBC under QAM modulation are figured out.
