This paper studies the random-coding exponent of joint source-channel coding\nfor the multiple-access channel with correlated sources. For each user, by\ndefining a threshold, the messages of each source are partitioned into two\nclasses. The achievable exponent for correlated sources with two\nmessage-dependent input distributions for each user is determined and shown to\nbe larger than that achieved using only one input distribution for each user. A\nsystem of equations is presented to determine the optimal thresholds maximizing\nthe achievable exponent. The obtained exponent is compared with the one derived\nfor the MAC with independent sources.\n
