论文摘要
近年来，正交设计的时空块代码（STBC）引起了极大的兴趣。但是，随着对更高容量方案的需求不断增长，Multiantenna传输技术必须支持并实现更高的符号传输速率。在本文中，我们专注于三个和四个传输天线方案。在过去的二十年中，尚未实现三个和四个传输天线的STBC方案，这些方案在正交，完全多样化，延迟效率和非常低的解码复杂性的同时，达到了很高的符号传输速率。这些计划迄今为止提出的，在达到速率或反之亦然的同时，与正交，延迟，多样性或解码复杂性进行了贸易。这项工作首先是解决此问题的同时实现所有期望的属性。 在这项工作中，我们仔细研究了设计较高符号传输速率STBC时必须考虑的各个方面。所提出的设计，特此称为Jagannath方案 - 对于4 x 3和4 x 4的配置是正交的，实现了完全多样性，并支持2个符号/s/hz的符号传输速率。设计方法遵循编码增益最大化方法。提出了对拟议的传输方案进行解码的低解码复杂性程序，并在不同的设置下在模拟中进行了广泛评估。拟议方案的性能与两个最先进的方案相比。 Aciod和Jafarkhani。 Jagannath 4 x 3显示出〜12 dB的表现优于ACIOD，而Jagannath 4 x 4表现出〜7 dB的出色性能，与4 bpcu的Jafarkhani相比。这激发了战术和商业通信系统中的Jagannath计划的采用，以有效地翻倍或扩展
Space Time Block Codes (STBCs) from orthogonal designs have attracted significant interest in recent years. However, with the growing demand for higher capacity schemes, the multiantenna transmission techniques must support and achieve higher symbol transmission rates. In this article, we focus on three and four transmit antenna schemes. For over two decades, STBC schemes for three and four transmit antennas that achieve a very high symbol transmission rate while being orthogonal, fully diverse, delay-efficient, and with very low decoding complexity have not been achieved. The schemes proposed so far trades off orthogonality, delay, diversity, or decoding complexity while achieving rate or vice-versa. This work is first of its kind to solve this problem while fulfilling all the desired properties. In this work, we carefully study the various aspects that must be considered in designing higher symbol transmission rate STBCs. The proposed designs, hereby referred to as, Jagannath schemes - for 4 x 3 and 4 x 4 configurations are orthogonal, achieve full diversity, and support a symbol transmission rate of 2 symbols/s/Hz. The design methodology follows a coding gain maximization approach. The low decoding complexity procedure to decode the proposed transmission schemes are proposed as well as extensively evaluated in simulations under diverse settings. The performance of proposed schemes are empirically compared to two state-of-the-art schemes; ACIOD and Jafarkhani. Jagannath 4 x 3 was shown to outperform ACIOD by ~12 dB while Jagannath 4 x 4 exhibited a ~7 dB superior performance in contrast to Jafarkhani at 4 bpcu. This motivates the adoption of Jagannath schemes in tactical and commercial communication systems to effectively double the throughput or to extend the
