TC-92-1 A thesis submitted in partial fulfillment of the requirement for the degree of Master of Engineering, School of Engineering and Technology Thesis (M.Eng.) - Asian Institute of Technology,1992 The intention of performing this work is to provide a procedure for code conversion from MH to MMR and vice versa. The thesis aims at proposing an adapter which could be connected to the conventional G3 fax machine and the composite unit would then communicate with a similar unit at the rate of 64 kb/s over ISDN. Thus, it permits the telefax customers to utilize the high speed B channel of ISDN for facsimile transmission using the conventional G3 fax machine. The task of performing the code conversion from MH to MMR and vice versa was accomplished by decoding the MH coded data into the raw form and then coding it into the MMR form at the transmitting end and then following the reverse procedure at the receiving end. The programs thus developed were tested on actual fax files and the results thus obtained were found to be satisfactory with no loss of image information. The effect of single bit error on the quality of the output was also studied and the thesis proposes an error correction scheme also .
