Abstract :
A novel realization scheme of space-time block code (STBC) is proposed by unequal power distribution between different transmitting (Tx) antennas at slow fading scenario. With optimal power distribution between the Tx antennas, the scheme can achieve a better performance than conventional STBC with equal transmitted power. Then we analyze and simulate the performance difference.
