Location：清華大學台達館 DELTA @R216

Abstract:
In multiple-access communication systems, many users share a common multiple access adder channel, where the signals from different users are superimposed to cause mutual interference. At the receiver side, the superimposed signals must be separated, even in the presence of noise.
In this talk, the signature coding problem for the multiple-access adder channel is considered, which is equivalent to the coin-weighting problem and the combinatorial detection problem. The bounds and some constructions for signature codes will be discussed. Finally, an application of the signature code for the random multiple access channel will be given.
