<p>A method for supporting calls between two mobile stations within a satellite communication system is disclosed. First, when signals transmitted by a first mobile station using a narrowband transmission format are received at a satellite relay station, the received signals are sampled and digitized. The sampled and digitized signals are then stored in a buffer at a first rate. The stored data is then read out of the buffer at a faster rate than the first rate and modulated onto a downlink frequency to create a wideband transmission format. The modulated signals are then transmitted to the second mobile station.</p> |
