Papr reduction using scs-slm technique in stfbc mimo-ofdm
TLDR
The utilization of circulant shift codeword from SCS technique with multiplication of phase factor of SLM technique in preparing several candidates for interleaving technique is proposed in MIMO-OFDM system for PAPR and BER performance improvement.Abstract:
The combination of MIMO and OFDM gives a very attractive option for high data rate communication in wireless communication system over frequency selective fading. However, MIMO-OFDM also inherent the PAPR problem from OFDM system. We proposed our SCS technique and modified SLM technique to be applied in diversity MIMO-OFDM system for PAPR and BER performance improvement. The utilization of circulant shift codeword from SCS technique with multiplication of phase factor of SLM technique in preparing several candidates for interleaving technique is proposed in MIMO-OFDM system. This approach gave a new solution of reducing high PAPR in MIMO-OFDM system. Moreover, by using diversity MIMO-OFDM which is STFBC, the improvement of BER performance also can be improved until 55%.read more
