최근에는 방송 서비스가 셀룰러 네트워크에 도입되었으며 매크로 다양성은 페이딩을 방지하는 효과적인 방법입니다. 본 논문에서는 다중 협력 기지국의 전체 안테나로 구성되고 모든 안테나가 등가의 다중 입력 다중 출력(MIMO) 시스템을 구성하는 매크로 다이버시티를 위한 일종의 분산 시공간 블록 코드(STBC)를 제안합니다. 이 코드는 HDFR-QOSTBC(High-Dimension-Full-Rate-Quasi-Orthogonal STBC)라고 하며 다음과 같은 특징을 가질 수 있습니다. (1) 특히 전송 안테나 수가 많은 경우 전송 안테나 수에 제한 없이 적용될 수 있습니다. (2) 코드의 전체 전송 속도는 3입니다. (XNUMX) 이 코드의 ML(Maximum Likelihood) 디코딩 복잡성은 제어 가능하며 다음으로 제한됩니다. Nt전체에 대해 /2-기호-디코딩 가능 Nt 송신 안테나. 그런 다음, 코드 종류에 대한 등가 채널의 구조를 완전히 분석하여 등가 채널의 고유 벡터가 일정하고 채널 구현과 독립적이라는 특성을 밝힙니다. 기호 선형 디코더. 또한 다양한 매크로 다양성 체계를 분석하고 성능 비교를 제공합니다. 시뮬레이션 결과는 제안한 방식이 소프트 결합 방식과 CDD(Cyclic Delay Diversity) 방식에 비해 상당한 성능 향상을 보여 방송 시스템에 실용적임을 보여줍니다.

Abstract: Recently, broadcast services are introduced in cellular networks and macro diversity is an effective way to combat fading. In this paper, we propose a kind of distributed space-time block codes (STBCs) for macro diversity which is constructed from the total antennas of multiple cooperating base stations, and all the antennas form an equivalent multiple input multiple output (MIMO) system. This code is termed High-Dimension-Full-Rate-Quasi-Orthogonal STBC (HDFR-QOSTBC) which can be characterized as: (1) It can be applied with any number of transmit antennas especially when the number of transmit antennas is large; (2) The code is with full transmit rate of one; (3) The Maximum Likelihood (ML) decoding complexity of this code is controllable and limited to Nt/2-symbol-decodable for total Nt transmit antennas. Then, we completely analyze the structure of the equivalent channel for the kind of codes and reveal a property that the eigenvectors of the equivalent channel are constant and independent from the channel realization, and this characteristic can be exploited for a new transmission structure with single-symbol linear decoder. Furthermore, we analyze different macro diversity schemes and give a performance comparison. The simulation results show that the proposed scheme is practical for the broadcast systems with significant performance improvement comparing with soft-combination and cyclic delay diversity (CDD) methods.
