Adaptive Coding and Modulation Waveform for Space Communication
(LEW-19478-1)
Overview
An Adaptive Coding and Modulation Waveform for Space Communication has been developed and demonstrated on a space-qualified software defined radio (SDR). The waveform utilizes the commercial Digital Video Broadcasting- Second Generation (DVB-S2) standard to provide a suite of modulation and encoding schemes, which allows the communication link to be dynamically adjusted to optimize performance. The waveform utilizes the Space Data Link Protocol (Consultative Committee for Space Data Systems (CCSDS) standard) to control the transmitter's mode of operation, using a BPSK/QPSK receiver. The waveform includes the ability to automatically compensate for non-linear channel impairments to improve the performance of high-order modulations.
