On PAPR Reduction Techniques in Mobile WiMAX
The mobile Worldwide Interoperability for Microwave Access (Mobile WiMAX) air interface adopts orthogonal frequency division multiple access (OFDMA) as multiple access technique for its uplink (UL) and downlink (DL) to improve the multipath performance. All OFDMA based networks including mobile WiMAX experience the problem of high peak-toaverage power ratio (PAPR). The literature is replete wit...
متن کاملPAPR Reduction and BER Performance for WiMAX on USRP N210 using GNU Radio
The test bed utilizes an open source GNU Radio software environment and the Ettus Research Universal Software Radio Peripheral (USRP N210) for performing SDR functionality, which reduces the cost and complexity of the system. This paper focuses on the implementation of an OFDM based WiMAX physical layer on a specific SDR, the GNU Software Radio (GSR). However, a major problem involved with OFDM...
متن کاملChannel Sounding and PAPR Reduction in OFDM for WiMAX Using Software Defined Radio
Abstract—This paper addresses the reduction of peak to average power ratio (PAPR) for the OFDM in Mobile-WiMAX physical layer (PHY) standard. In the process, the best achievable PAPR of 0 dB is found for the OFDM spectrum using phase modulation technique which avoids the nonlinear distortion. The performance of the WiMAX PHY standard is handled by the software defined radio (SDR) prototype in w...
