| Abstract(in English) | This paper proposes a novel spread spectrum modem for random access satellite communication. The proposed modem employs a parallel structure to ensure detection of packet arrival. Code timing detection with a combination of a coarse detector and a fractional error detector reduces the sampling rate while maintaining the BER performance. An insymbol pilot multiplexing scheme is also proposed for fast and stable carrier synchronization with a simple hardware. A performance evaluation shows that the proposed modem achieves the UW miss-detection probability of better than 10^<-4> at the E_b/N_o of 0 dB. The overall BER performance achieved in experiments well agrees simulation and theoretical values. |
