Abstract

For a reliable communication the transmitted information should reach the destination as such. The information that we transmits get altered due to many reasons. One of the main reasons in communication system is soft error. Even though soft error does not make any physical damage to the communication system, it alters the values stored in the system. It can alter the transmitted message. Complex circuits are affected by soft errors in electronic circuits. Algorithmic-Based Fault Tolerance (ABFT) techniques are used to detect and correct errors in the electronic circuits. Fast Fourier transforms (FFTs) plays an important role in many communication and signal processing systems. Fast Fourier transforms (FFTs) are the basic building block in many systems. In real time application systems, numbers of blocks operating in parallel are used. A lot of techniques are available to detect the soft error and correct it. All these assume that there can only be a single error in the circuit. Reduced Precision Redundancy (RPR) technique is used in this paper to detect and correct multiple errors.
