“…The above-mentioned problems can be solved by using a synchronization algorithm tracing the phase or frequency of the received signal on a sample-by-sample manner, e.g. a software PLL [9], but at the expense of troublesome selection of the loop's bandwidth providing both wide capture range and sufficient robustness when the loop works in the locked state.…”

The paper is related to an adaptive satellite communication system for data transmission from small, low cost, low Earth orbit satellites. Tests run in a set-up consisting of a number of software-defined radio (SDR) modules operating as a satellite, a ground station, and a satellite channel simulator, have shown that by changing modulation scheme and code rate one can obtain increase of amount of data which can be downloaded from a satellite during a single pass over a ground station approximately by a factor of 2. To determine data rates obtainable in an SDR system using a common personal computer as a digital signal processing device, execution times of particular processing steps involved in the reception process were measured.
