| Abstract(in English) | In this paper, the decoding scheme of Reed-Solomon (RS) coded parallel combinatorial spread spectrum (PC-SS) communication systems is investigated in Rayleigh fading channel. Use of channel state information can provide error rate performance improvement in RS coded PC-SS systems by using error-and-erasure decoding. In the PC-SS systems, several sequences are selected and transmitted among preassigned PN sequences to convey data. Thus channel state information can be easily achieved in the PC-SS systems by using correlator outputs in the receiver. In this paper, we proposed two methods to achieve erasure location information. Simulation results show that the required E_b/N_O at 10<-3>BER with the proposed scheme is 2.5dB less than that with error-only decoding. |
