... Moreover for the SSC case, a compact and quite flexible formula of the ergodic capacity for integer values of m is presented. For the SC case, we present a new expression for the ergodic capacity ... we derive closed-form expressions for the ergodic capacity of dual EGC, SC, and SSC systems. For the EGC and SSC cases, we extend the work in [8] by allowing...
