Performance Advantage of Joint Source-Channel Decoder over Iterative Receiver under M-ary Differential Chaotic Shift Keying Systems Conference Paper uri icon

abstract

  • 2016 IEEE. In order to improve the error performance of M-ary differential chaotic shift keying (DCSK) systems over multi-path fading channel, two types of iterative structures have been employed in receiver design. One is joint source-channel decoder (JSCD), the other is iterative receiver (IR). Although several works have separately addressed the advantages of IR and JSCD, it is not clear which design provides more iterative gain for M-ary DCSK systems over multi-path fading channels. In this work, we employ the extrinsic information transfer (EXIT) chart technique to analyze the iteration behavior of JSCD and IR. Simulation results suggest that with enough source redundancy, JSCD outperforms IR under M-ary DCSK systems over multi-paths fading channels.
