SGER: An Exploration of MIMO Communication via the Optimization of a Novel Space-Time Architecture

该建议探讨了一种新的空时架构称为堆叠正交空时（SOST）的设计编码/调制方案和相关的信号处理和解码算法的多输入多输出（MIMO）无线信道。它结合了基于正交设计和垂直分层（V-BLAST）的两种著名架构的互补特性。与正交设计不同，SOST非常适合具有多个接收天线的系统，并且在大部分容量下表现良好。与V-BLAST不同，SOST结构可以在小的复用增益下提供完全的分集和优异的性能。

This proposal explores a new space-time architecture called Stacked Orthogonal Space Time (SOST) for designing coding/modulation schemes and associated signal processing and decoding algorithms for multi-input multi-output (MIMO) wireless channels. It combines the complimentary properties of two well-known architectures based on orthogonal designs and vertical layering (V-BLAST). Unlike orthogonal designs, SOST is well-suited for systems with several receive antennas and would perform well at large fractions of the capacity. Unlike V-BLAST, the SOST architecture can provide full diversity and excellent performance at small multiplexing gains.
