Abstract :
A new power efficient concatenated space-time block-code (STBC) consisting of a simple 4-states rate 1/2 convolutional code and an orthogonal STBC (oSTBC) with suitable labeling of 16QAM symbols over Rayleigh fading channel with two transmit and one receive antenna is proposed by means of extrinsic information transfer (EXIT) chart analysis. This scheme can achieve a bit error ratio (BER) below 10-4 for Eb/No = 4.4 dB at a transmission rate of 2 bits per channel use, which seems to be highly efficient w.r.t. simplicity and power efficiency.
