摘要：The main aim of this paper is to reduce the computational complexity versions of a low cost OFDM (orthogonal frequency division multiplexing) modulation schemes for the implementation of clustered OFDM system for the data transmission in the pass band frequency. Among The proposed schemes, which are named HS-OFDM I (Hermitian symmetric-OFDM) & HS-OFDM II , HS-OFDM II Can offer computational complexity reduction in comparison with the SSB-OFDM, HS-OFDM I ,HS-OFDM & OFDM system when the length of the OFDM symbol increases and all schemes BER performance is same in PLC system. Results shows that HS-OFDM I has a lower complexity than traditional HS-OFDM, and HS-OFDM II further reduces the complexity and achieves the lowest complexity implementation among the five schemes Among that, show bit error rate (BER) for different modulation techniques (4-QAM , 16-QAM. 64-QAM) by considering same computational complexity.
