摘要：Beside random errors, burst error studies have attracted quite some attention. Most communications now being open to atmospheric and other disturbing effects, the error patterns are mostly in the form of bursts. In fact usually the messages are long and the strings of bursts may be short repeating in a vector itself. The idea of repeated bursts, introduced by Berardi, Dass and Verma has opened this area of study. In this paper we obtain results on weights of all vectors having 2-repeated bursts of the same size. Another section is devoted to the study of vectors having 2 repeated bursts with weight constraints. The study can help developing more efficient codes with these vectors as error patterns.
