Note on Tong's burst-trapping technique (Corresp.)

An extension of Tong's burst-trapping technique is presented that allows usage in more complex channels. In particular, the guard space after a burst need not be error free, but must contain a smaller number of random errors than normal. Special types of codes are needed for this method, such that some redundancy can be discarded and the remaining word can still correct for errors on a reduced scale. Examples are given.
