연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

For the sake of the potential ability of overcoming interference in TD-SCDMA(time division-synchronous code division multiple access) systems, pilot signal is adopted, but the presented TD-SCDMA protocol has not considered the Rake technique for their mobile terminals. This paper developed a RAKE re...

  • A sliding correlation of the proposed Rake receiver is performed at each receiving end between the received signal and the locally generated version of the pilot signal to obtain the finger positions This paper has investigated the performance of Rake receiver in the complex case of multipath and multiusers, and pointed that there is a range of BER for Rake receiver. Numerical results have been used to demonstrate the performance of the proposed RAKE receiver in terms of bit error probability under multipath fading propagation and multiusers conditions.
  • Additionally, a PN signal(pilot signal) from a TD- SCDMA base station is added to 나此 downlink transmitted signal in order to perform the channel parameter estimation.
  • To solve the above problems and improve the communication quality of the downlinks of TD-SCDMA, this paper provides an algorithm and a Rake circuit structure, which are of channel parameter estimation in a RAKE receiver based on TD- SCDMA burst structure. Theory analysis and numerical simulation results are used to demonstrate the performance of the proposed RAKE receiver in terms of bit error probability under multipath fading propagation conditions, even compared with the SIR Rake receivers[11], [12].
