Abstract :
In Iacobucci and DiBenedetto (1997), an extension of the deterministic feedback code proposed by Ozarow (1984) for the two-user Gaussian multiple access channel (MAC) was presented; Ozarow´s code was extended to the case of U-users (U⩾2) in the specific case in which all users have equal power. In the present paper, a performance analysis of the proposed code compared to BCH codes is reported. It is shown that a large gain over BCH codes with the same transmission rate and same redundancy is obtained with the new code, if redundancy exceeds a critical value which was determined by computer simulation
