사물인터넷(IoT)의 출현으로 짧은 패킷 전송이 미래 무선 통신을 지배하게 될 것입니다. 그러나 기존의 일관성 있는 복조 및 채널 추정 방식에는 큰 파일럿 오버헤드가 필요하므로 다중 경로 페이딩 시나리오의 짧은 패킷에는 매우 비효율적일 수 있습니다. 본 논문에서는 MOCZ(Modulation on Conjugate-Reciprocal Zeros)와 TBCC(Tail-Biting Convolutional Code)의 결합을 기반으로 채널 상태 정보 없이 비동기식 복조 및 디코딩 방식을 설계하는 새로운 파일럿 없는 짧은 패킷 구조를 제안합니다. CSI) 트랜시버에서. 성상 집합의 구성 방법과 복조 규칙을 제공한다. M-ary MOCZ. 낮은 복잡성의 로그 가능성 비율(LLR)을 도출하여 M-ary MOCZ는 공동 코딩 및 변조 방식을 위해 에너지와 대역폭 효율성 간의 합리적인 균형을 제공합니다. 시뮬레이션 결과는 우리가 제안한 방식이 다중 경로 페이딩 채널을 통해 파일럿 기반 일관성 변조 방식에 비해 상당한 성능 및 처리량 이득을 얻을 수 있음을 보여줍니다.

Abstract: With the advent of the Internet of Things (IoT), short packet transmissions will dominate the future wireless communication. However, traditional coherent demodulation and channel estimation schemes require large pilot overhead, which may be highly inefficient for short packets in multipath fading scenarios. This paper proposes a novel pilot-free short packet structure based on the association of modulation on conjugate-reciprocal zeros (MOCZ) and tail-biting convolutional codes (TBCC), where a noncoherent demodulation and decoding scheme is designed without the channel state information (CSI) at the transceivers. We provide a construction method of constellation sets and demodulation rule for M-ary MOCZ. By deriving low complexity log-likelihood ratios (LLR) for M-ary MOCZ, we offer a reasonable balance between energy and bandwidth efficiency for joint coding and modulation scheme. Simulation results show that our proposed scheme can attain significant performance and throughput gains compared to the pilot-based coherent modulation scheme over multipath fading channels.
