Abstract :
The capacity region of the two-user Gaussian CDMA channel is shown to be achievable when the (stationary, ergodic) noise is not Gaussian, using a decoder matched to the Gaussian distribution. Similarly, the capacity of the exponential server timing channel is shown to be achievable when the service distribution is not exponential, using a decoder matched to the exponential distribution. The code-book in either case will depend on the true channel
