Performance Analysis of Reed-Solomon Coded M-ary FSK Modulation in Nakagami Fading Channels
강희조,Kang Heau-Jo The Korea Institute of Information and Commucation 2006 한국정보통신학회논문지 Vol.10 No.7
In this paper we analyze the performance improvement of the M-ary FSK systems for low power and low data rate applications. This contribution presents a unified analysis of its MRC diversity, uncoded and performance in A WGN, m=2, m=3, Rayleigh and one sided Gaussian fading channels using optimum noncoherent demodulation with Reed-Solomon(RS) codes. The results of this paper should be useful as benchmarks of obtainable performance and as a reference for validating the results of simulation studies when slow fading models are applicable. 본 논문에서는 낮은 전력과 낮은 데이터 율의 M-ary FSK 시스템의 응용하고 성능 개선에 관해서 분석한다. 제안 시스템에서는 최대비 합성 다이버시티, 부호화와 비 부호화 일 때 가우시안 잡음, m=2, m=3, 레일리, 반가우신안 페이딩 채널에서 리드솔로몬 부호화를 이용하여 최적의 변조 값을 구하였다 . 시뮬레이션 분석 결과로부터 슬로우 페이딩 모델에 응용이 적당함과 웅용시스템에 유용함을 확인하였다.

인구의 증가와, 도시의 거대화, 교통의 발달 이상기후 등으로 인한 재해 재난이 급증하고 있으며 피해규모도 점차 확대되고 있다. 자연재해나 인위적 재난은 발생자체를 막을 수는 없으나 인위적 재난일 경우에는 IT기술이 발전함에 따라 재해를 미리 예방 및 완화할 수 있는 센서 기술 및 모니터링기술에 의해서 사전에 감지하여 피해정도를 줄일 수 있다. 본 논문에서는 방재정보통신시스템 응용 및 표준화 동향에 대하여 연구하고자 한다. Disasters are increasing rapidly due to increase of population, gigantism of cities, advancement of traffics, and abnormal weather phenomena, and the scale of damages is also getting wider. Natural disasters and artificial disasters are almost unavoidable, but in the case of artificial disasters, we can decrease damage levels using constantly developing IT technology, such as sensing and monitoring technology which can be used for preventing and mitigating disasters. In this paper, we study the disaster prevention information communication system's application and standardization trend.

Disasters are increasing rapidly due to the increase of population, gigantism of cities, advancement of traffics, and abnormal weather phenomena, and the scale of damages is also getting wider. Natural disasters and artificial disasters are almost unavoidable, but in the case of artificial disasters, we can decrease damage levels using constantly developing IT technology, such as sensing and monitoring technology which can be used for preventing and mitigating disasters. Emergency Preparedness Telecommunications Systems, the system make a gradual complication according to development of information communication technology. An emergency telecommunication function was the focus of communication service for an emergency communication and restoration at the disaster occurrence area at the beginning, but the communication function of disaster prevention area is imported. In this paper, we study on development technology, construction plan of next-generation disaster wireless communication and proposed the systems.

The development of information society together with information telecommunication's influence on the human society is a ripple effect and getting wider. Among those ripple effects the disaster prevention is in the public eye in the present day. On the way to the ubiquitous society the main techniques to be concerned in ubiquitous sensor networks are the field of damage of storm and flood, safety facilities, traffic safety, industrial safety, energy safety, fire fighting, specific safety of radioactivity escape incident, environmental pollution, sea pollution, mountain and forrest disaster so on. In this paper the information technique based on the disaster prevention information telecommunication system's industry union and its requirement technology and application are studied.
