Abstract :
In this paper, we propose two RAKE receiving methods of the chirp spread spectrum (CSS) system to suppress the influence of the multipath-fading channel. The first one has low complexity by using the simple accumulator to collect the energies of the multi-paths. The second one can enhance the PER performance of the differential detection by adopting the concept of the multiple-symbol differential detection (MS-DD). We verified the proposed architectures through Monte-carlo simulations in diffuse channels. The simulation results show that the RAKE receiving methods can efficiently reduce performance degradation in multipath channel.
