Discrete Sine Transform Based OFDMA System for Wireless Broadband Communications
Exploiting the energy compaction property of the discrete sine transform (DST), this paper, implements the DST rather than the discrete Fourier transform (DFT) as a basis function for the OFDMA system, the proposed system is called the DST-OFDMA. The performance of the proposed DST-OFDMA system is studied and compared to the conventional DFT-OFDMA system, and the recently proposed discrete cosine transform (DCT) based OFDMA system using computer simulation. The performance study and comparison is carried based on bit error rate (BER) and peak-to-average power ratio (PAPR) metrics. Simulation results show the improvement provided by the proposed system in terms of BER performance with approximately same PAPR performance when compared to other systems. The simulation results for the proposed systems are presented to demonstrate the effectiveness of the proposed systems for broadband communications.
