摘要:
The distance distribution of a binary code C is the sequence (B-i)(i)(n)=0 defined as follows: Let B-i(w) be the number of codewords at distance i from the codeword w, and let B-i be the average of B-i(w) over all w in C. In this correspondence we study the distance distribution for codes of length n and minimal distance delta n, with delta > 0 fixed and n --> infinity. Our main aim is to relate the size of the code with the distribution of distances near the minimal distance.
