A Preposed Implementation of Space-time Block Encoding
-
摘要: 提出了一种将信道编码和星座图相结合的方法来实现前置空时分组编码。该方法将原来在调制阶段完成的工作提前至编码阶段完成。因此，其具有发射系统结构简单、通用和易于实现的优点。仿真结果表明，在简化了硬件结构的同时，该方法拥有与常规方法基本相同的性能。Abstract: A preposed implementation of space-time block encoding using channel encoding and constellation mapping is presented.It implements the space-time block encoding at the step of channel coding instead of modulation. Thus it has simple and generalized construction of the transmitters and easy implementation. The simulation indicates that this method has performance similar to the conventional ones.
