The problem of bounding the reliability function of a multiple access channel (MAC) is studied. Two new upper bounds on the error exponent of a two-user discrete memoryless (DM)-MAC are derived. The first bound (sphere packing) is an upper bound on the exponent of the average probability of error and is the first bound of this type that is zero outside the… CONTINUE READING
