We consider a new signal-code construction for a special class of multiple access system over vector-disjunctive channel when users transmit some vector of bits of finite length L. We propose a special encoding and decoding algorithms for such transmission scenario. Our suggested methods of encoding and decoding on one hand have acceptable complexity for a wide range parameters and on other one a decoding rule we considered has a performance very close to maximum likelihood (ML) decoding. We present some simulation results for relative sum-rate of our construction and for frame error rate (FER) in the case of different number of active users and different code constructions. Simulation results we obtained allow us to conclude that our scheme has a good performance even for very short codes.
