In this paper, we design and analyze a soft handoff algorithm for code-division multiple access (CDMA) systems in a Rayleigh fading environment. For each mobile, this algorithm sel...

We consider the problem of rate allocation in a fading Gaussian multiple-access channel (MAC) with fixed transmission powers. Our goal is to maximize a general concave utility func...
