Abstract

SUMMARYThis paper describes the implementation of the first enhanced spread spectrum aloha demodulator, based on an innovative architecture which combines software‐defined radio with processing via commercial graphics processing units. The validation tests performed both in laboratory conditions and directly on the satellite EUTELSAT 10A are presented. The performance assessment results obtained via satellite validate the theoretical results to a sufficient degree to make enhanced spread spectrum aloha technology a viable option for low‐power mobile and fixed terminals, thus encouraging the growth of satellite mass market applications.
