Abstract :
OFDM technology combined with STC has been used widely in modern communication systems, due to offering many advantages such as improving system capacity. Meanwhile it faces the mutual interference, such as CCI, which generated by multi-antenna transmitting at the receiver. Based on those advantages coming from the combination of STC-OFDM with WHT and the combination of STC-OFDM with ABF, an algorithm is proposed to suppress co-channel interference. Theoretical analysis and computer simulation showed the proposed algorithm could improve Symbol Error Rate performance and suppress CCI in STC-OFDM communication systems.
