Abstract : Cyclic codes are practical and efficient codes which protect against the effects of additive errors. However their effectiveness, like that of block codes, requires correct word synchronization at the decoder. Cyclic codes with symbols from a general finite field are modified so that they are also capable of protecting against misframing at the decoder. These codes are modified by altering their distance structure. There are a number of techniques which can be employed. Each method affects different aspects of the code's performance; therefore a complete and comprehensive coverage of all techniques is given. Results for each modification approach are given for three types of protection from the simultaneous occurrence of additive errors and synchronization errors. (Author)
