  The ergodic and outage channel capacity of different optimal and suboptimal
combinations of transmit power and modulation rate adaptation strategies over a
joint fading and two-path shadowing (JFTS) fading/shadowing channel is studied
in this paper. Analytically tractable expressions for channel capacity are
obtained, assuming perfect channel side information (CSI) at the receiver
and/or the transmitter with negligible feedback delay. Furthermore, the impacts
of the JFTS parameters on the channel capacity achieved by these adaptive
transmission techniques are determined.
