우리는 SS-CDMA 유연한 무선 셀룰러 네트워크의 다운링크를 위한 패킷 SS-CDMA 방식을 제안했습니다. 전송 패킷은 11칩 Barker 코드로 구성된 동기화 블록과 직교 확산 코드로 구성된 정보 블록으로 구성됩니다. 칩 동기화는 단축 코드 SAW(Surface Acoustic Wave) 정합 필터를 사용하여 수행됩니다. 코드 역확산은 인라인 역확산기를 사용하여 수행됩니다. 직교 m-시퀀스를 사용하여 63개 채널의 다중 채널 다운링크를 설계할 수 있습니다. 시뮬레이션 결과, 다중 경로 환경에서 이론값의 저하 없이 15개 이상의 채널을 사용할 수 있는 것으로 나타났습니다. 패킷 SS-CDMA 모뎀은 2.4GHz 프런트엔드 SAW 정합 필터를 사용하여 구현되었습니다. 분해 Eb/N0 0.5dB 미만은 XNUMX채널 다중화를 통해 실험적으로 달성되었습니다.

Abstract: We have proposed the packet SS-CDMA scheme for downlink of SS-CDMA flexible wireless cellular network. Transmission packet is framed with synchronization block with 11 chip Barker code and information block with orthogonal spreading code. The chip synchronization is carried out using short code surface acoustic wave (SAW) matched filter. The code de-spreading is carried out using in-line de-spreader. Multi-channel downlink of 63 channels can be designed using orthogonal m-sequence. Simulation results show more than 15 channels without degradation from theoretical value can be used under multi-path environment. The packet SS-CDMA modem has been implemented using a 2.4 GHz front-end SAW matched filter. Degradation of Eb/N0 of less than 0.5 dB is experimentally achieved with four-channel multiplex.
