摘要

本文研究了复合分集编码(CDC)和差错控制编码(ECC)的联合应用，以提高跨多天线、OFDM块和OFDM子载波的分集增益。给出了基于CDC和ECC的空时频码(stfc)的一般分集分析。从ECC到CDC的映射设计是有效开发多样性潜力的关键。本文给出并证明了三维CDC与ECC、位交织编码复分集编码(BICCDC)和符号交织编码复分集编码(SICCDC)联合构建全分集的充分条件。为了降低解码过程的复杂性和延迟，还引入了多流架构。

Three-dimensional combined diversity coding and error control coding: Code design and diversity analysis

This paper investigates joint complex diversity coding (CDC) and error control coding (ECC) to increase diversity gains across multiple antennas, OFDM blocks, and OFDM sub-carriers. A general diversity analysis for joint CDC and ECC based space-time-frequency codes (STFCs) is provided. The mapping designs from ECC to CDC are crucial for efficient exploitation of the diversity potential. This paper provides and proves a sufficient condition of full diversity construction with joint 3D CDC and ECC, bit-interleaved coded complex diversity coding (BICCDC) and symbol-interleaved coded complex diversity coding (SICCDC). A multi-stream architecture is also introduced to reduce the complexity and latency of the decoding process.
