ABSTRACT:
In a communication system, a signal transceiver generates an upper pre-encoding symbol stream and a lower pre-encoding symbol stream by pre-encoding an upper transmission vector and a lower transmission vector according to a pre-encoding scheme when the upper and lower transmission vectors to be transmitted are input. The signal transceiver generates a space-time mapping matrix by space-time mapping the upper and lower pre-encoding symbol streams according to a space-time mapping scheme based on the number of transmit antennas to be used in the signal transceiver. The signal transceiver generates and transmits a codeword according to whether a null transmission is present in the space-time mapping matrix.
