In this work we investigate the limits on information-transmission in the finite-lifetime channel. We derive an upper bound for the information that can be transmitted, and we introduce an optimum acausal scheme for power-allocation. Furthermore, we introduce more practical but nevertheless efficient schemes for allocating power, and we compare their performance with the optimum scheme in a vehicle-to-vehicle communication scenario.
