Abstract

 ACCURATE FAULT DETECTION IN TERM OF THE PARAMETERS SUCH AS VOLTAGE, CURRENT, GAIN AND OVERALL CONSUMED ENERGY IN DIGITAL AND ANALOG CIRCUITS NEEDS CIRCUIT SIMULATING USING ACCURATE PARAMETERS UNDER THE REAL CONDITION AND REAL INPUTS. THE REASON FOR NEEDING THE FAULT CORRECTION OPERATION IN THE DESTINATION IS REDUCTION OF THE TRANSMISSION FAULT AND LACK OF REQUIRING THE TRANSMITTERS’ POWER INCREASE. OF COURSE, IS SHOULD BE NOTED THAT SINCE THE FAULT CORRECTION OPERATION IN REQUIRED TO ADD EXTRA INFORMATION TO THE TRANSMITTED DATA, THE TRANSMISSION RATE WOULD BE HIGHER WHICH NEEDS MORE BANDWIDTH. ALSO, BLOCK CODES, CONVOLUTION CODED AND MIX OPERATION ARE DESCRIBED. USING THE BLOCK CODING WHICH IS PERFORMED ON THE BIT’S BLOCKS, IT IS POSSIBLE TO REDUCE THE FAULT IN DECODED DATA. USING THE CONVOLUTION ENCODING AND HAMMING CODE WHICH IS APPLIED ON EACH OF THE BITS, IN ADDITION TO REDUCING THE FAULT POSSIBILITY IN DECODED DATA, IT IS POSSIBLE TO CHANGE THE CODE RATE CONSIDERING THE CHANNEL CONDITIONS SUCH AS RAINING ETC. MAKING USE OF THE MIXING OPERATION ALSO CAUSES THE SECURITY OF THE TRANSMITTED INFORMATION AGAINST FADING, BATCHING AND ETC. IN THIS PAPER, BY INVESTIGATING THE FAULT CORRECTION METHODS, WE WILL INVESTIGATE THE LOW COST FAULT DETECTION (LCFD) IN ALL SINGLE-BIT COMPLEX CIRCUITS AND EVALUATE THE CHARACTERISTICS OF THE CIRCUIT IN VICINITY OF THE FAULT.
