STBC codes for generalized spatial modulation in MIMO systems
We propose and analyze a generalized spatial modulation scheme. In this GSM multiple antenna will be active during the transmission. A spatial modulation (SM) scheme with multiple active transmit antennas, named as multiple active spatial modulation (MA-SM). In MIMO multiple transmitting antennas are allowed in the SM system to transmit different symbols at the same time instant. Here the Space Time Block Codes are used instead of Spatial Modulator. Compare to SM in STBC the bit error probability is good and signals to noise ratio will be increased. When we will increase the number of transmit and receive antennas using spatial modulator to encode the transmitted datas the bit error rate is high and signal to noise ratio is good for 2×2 MIMO. For 4×4 MIMO the bit error rate is reduced and signal to noise ratio is poor. So to get a Good BER Vs SNR and FER Vs SNR the STBC is used instead of spatial modulator. And for better result the inter symbol distance will be increased in the data transmission and for each symbol the rotation angle will be applied. In GSM 16-QAM modulation is used. So here BPSK, QPSK, 16-QAM modulator and 8 PSK are compared. When Compare to all modulation techniques BPSK modulation is better for good BER Vs SNR and FER Vs SNR.
