A new software approach for real time OFDM

This paper discusses real time implementation of a new software defined radio (SDR) for orthogonal frequency division multiplexing (OFDM). The proposed SDR is implemented on a single PC, which does not include any external hardware and solely rely on the capabilities of the PC. A step by step comparison of the proposed SDR with the real world system for OFDM is presented and the errors encountered by the proposed SDR due to sampling offsets are also discussed. Since the proposed SDR does not include any external hardware, its portability is tremendous and upgradation is economical, and the approach can be extended to other communication techniques. The SDR is a multi-standard device and a flexible and economical approach for communication because it incorporates the newer technologies without considerable change of hardware.
