PAPR Reduction in OFDM using Channel Coding in GNU Radio
The fundamental block of WiMAX (Worldwide Interoperability for Microwave Access) PHY layer is Orthogonal Frequency Division Multiplexing (OFDM). The main issue raised in OFDM is high Peak to Average Power Ratio (PAPR) due to multicarrier signal. This paper proposes architecture for PAPR reduction to improve network performance of WiMAX in urban areas where typically Non-Line of sight communicat...
متن کاملFrequency and Timing Offset Analysis in OFDM using GNU Radio
To enhance the performance and reduce the Inter Symbol Interference (ISI) at enhanced data rates in wireless communications, Orthogonal Frequency Division Multiplexing (OFDM) is being used. The performance of OFDM is degraded due to frequency and timing offsets which increase the Bit Error Rate (BER) in the wireless communication. Frequency offsets are caused due to difference between transmitt...

متن کاملImplementation of OFDM-based Superposition Coding on USRP using GNU Radio
This report summarizes our PHY layer implementation of a OFDMbased superposition coding system. In theory, multi-user techniques such as superposition coding (SPC) are known to improve throughput in wireless networks. However, in order to understand their practical limitations, it is imperative to actually implement and experiment with such techniques in a realistic setting. In this report, we ...
متن کاملConcatenated Coding in Ofdm for Wimax Using Usrp N210 and Gnu Radio
A software Defined Radio (SDR) device employs a reconfigurable hardware (Universal Software Radio Peripheral-USRP) that may be programmed over-the-air or software (GNU Radio) to function under different Wireless standards. This paper analyzes the effect of various parameters such as channel noise, frequency offset, timing offset, timing beta, FLL (Frequency Lock Loop) bandwidth, Costas loop (ph...
