Signature Code for Multiple-Access Adder Channel

概要

論文の詳細を見る
We survey error-correcting signature codes for multiple-access adder channel. First, we give the recursive construction of a (k+1)-ary signature code with minimum distance 2^<j-1>. Also we give the decoding rule for the signature code, consisting of error correction and user identification. Second, we give the construction of binary error-correcting signature code. By using a Hadamard matrix of order n, we construct a binary signature code with the minimum distance of n/2. These (k+1)-ary and binary codes are used to identify users through the multiple-access adder channel, even in the presence of channel noise.
