  We consider the capacity of memoryless finite-state multiple access channel
(FS-MAC) with causal asymmetric noisy state information available at both
transmitters and complete state information available at the receiver. Single
letter inner and outer bounds are provided for the capacity of such channels
when the state process is independent and identically distributed. The outer
bound is attained by observing that the proposed inner bound is tight for the
sum-rate capacity.
