Reduction of PAPR in MIMO-OFDMA system by using Daoud technique LDPC codes: article / Nur Farahana Mat Khairi
The high peak average power ratio, PAPR and also bit error rate, BER appears the be the main disadvantage as they are viewed as important implementation issues in communication system. These two major drawbacks were considered extensively in MIIVIO OFDMA which can result in significant distortion. T...

The high peak average power ratio, PAPR and also bit error rate, BER appears the be the main disadvantage as they are viewed as important implementation issues in communication system. These two major drawbacks were considered extensively in MIIVIO OFDMA which can result in significant distortion. These large peaks increase the amount of intermodulation distortion resulting in an increase in the error rate. In this paper, the proposed study is based on PAPR reduction by the implementation of Low Density Parity Check, LDPC using Daoud Technique. This paper also present the significant to simulate the bit error rate, BER to provide the system with good performance and achieving maximum diversity order which will improve the whole system in terms of BER performance. Comparison of PAPR and BER is carried out for LDPC and Daoud LDPC in MIMO OFDMA. The simulation result shows that the Daoud LDPC codes gives a slight better reduction of PAPR and BER with maximum diversity order achievement when compared to conventional LDPC codes. |
