Abstract

This paper describes a double-hop on board signal processing experiment over the Olympus satellite. The key component of this experiment is a recently developed SAW-based group demodulator. The double-hop experiments used QPSK/FDMA for the uplink and a single QPSK/TDM for the downlink. Results in terms of probability of bit error of the QPSK signal and the short term fading characteristics of the channel are given
