본 논문에서는 스태거 버스트 파일럿을 사용하는 업링크를 위한 새로운 일관성 있는 CDMA 채널 구조와 그 검출 알고리즘을 제안합니다. 업링크에서 셀의 모바일은 겹치지 않는 시간 슬롯에서 주기적 버스트를 전송하여 파일럿 채널을 공유하므로 일관성 있는 감지가 가능합니다. 업링크 용량을 분석하고 용량 공식을 도출합니다. DMCE(이중 모드 채널 추정기)는 파일럿 기반 채널 추정(PBCE)과 데이터 기반 채널 추정(DBCE)으로 구성됩니다. 제안된 DMCE 알고리즘은 파일럿 버스트가 주기적으로 DMCE 동작을 시작하기 때문에 가우스 잡음과 도플러 편이가 있는 경우에도 매우 안정적입니다. 무시할 수 있는 손실(0.068dB) Eb/N0 버스트 파일럿 도입으로 인한 결과입니다. 이상적인(0km/h) 일관성 감지와 비교할 때 필요한 Eb/N0 160km/h의 속도에 해당하는 도플러 편이는 2.0dB 미만으로 저하됩니다. 시뮬레이션 결과에서도 채널 용량이 증가한 것으로 나타났습니다. DMCE에 일부 추가 상관기가 필요하더라도 버스트 파일럿은 추가 복잡성 없이 구현될 수 있습니다. 이러한 개선은 비공유 파일럿을 사용하는 응집성 CDMA 검출기에 대한 이전에 발표된 연구와 비교할 때 중요합니다.

Abstract: This paper proposes a new coherent CDMA channel structure for the uplink with staggered burst pilot and its detection algorithm. In the uplink, mobiles in a cell share a pilot channel by transmitting periodic bursts in nonoverlapping time slots, which enables coherent detection. We analyze the uplink capacity and derive the capacity formula. The dual mode channel estimator (DMCE) consists of pilot-based channel estimation (PBCE) and data-based channel estimation (DBCE). The proposed DMCE algorithm is very stable in the presence of Gaussian noise and Doppler shift because the pilot burst initiates the DMCE operation periodically. A negligible loss (0.068 dB) in Eb/N0 results from the introduction of the burst pilot. When compared with ideal (0 km/h) coherent detection, the required Eb/N0 in Doppler shift, corresponding to the speed of 160 km/h, is degraded less than 2.0 dB. The simulation result also shows increased channel capacity. The burst pilot can be implemented without added complexity even though some extra correlators are needed for the DMCE. This improvement is significant compared to previously published studies of coherent CDMA detectors with non-shared pilots.
