Spectrum Sensing Measurement using GNU Radio and USRP Software Radio Platform
Spectrum utilization can be significantly improved by adopting cognitive radio (CR) technology. Such radios are able to sense the spectral environment and use this information to opportunistically provide wireless links that meet the user communications requirements optimally. To achieve the goal of cognitive radio, it is a fundamental requirement that the cognitive user (CU) performs spectrum ...
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 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...
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...
