Abstract :
Space-time block codes providing transmit diversity for communication over multiple transmitter channels are considered. A scheme giving ad possible 4 antenna, 4 epoch space-time block codes is presented. The scheme generalizes to an arbitrary number of Tx antennas, optimizing the transmission delay and modulator rate when full diversity is required. For four transmit antennas, the antenna power spectrum of the space-time block code is optimized
