Adaptive power transmission schemes for meteor-burst communication

Different transmission schemes are known in the literature to optimize the performance of systems operating on the meteor-burst channel. In general these schemes can be classified into variable or fixed rate schemes. In this paper we propose and analyze a new adaptive-power, fixed-rate, transmission scheme for meteor-burst channel. In this scheme, symbols with low power are transmitted at the beginning of the burst while symbols with high power are transmitted at the end of the burst. A method to implement the proposed scheme is described and its performance is compared to the performance of systems with fixed power transmission. It is found that a saving of approximately 37% in the transmitted energy can be achieved using the adaptive power scheme compared to systems with fixed-power transmission
