多层交织分复用空时码系统的设计

Design on the System of Multi-layer Interleave Division Multiple Space Time Code

IDMA技术以其抗多径干扰性好、接收复杂度低等优点成为第四代移动通信的关键技术之一。多层交织分多址复用时空码(ML-IDM-ST)系统是将空时码(STC)思想和IDMA系统相结合的演化而来,它具有接收简单,复杂度低和高吞吐量等优点。本文描述了多层交织分复用空时码系统(ML-IDM-ST)的基本原理和算法流程并对其发展前景进行了预测。

IDMA becomes one of the key technologies in the fourth-generation mobile communications for its＇ good performance and low complexity, ML-IDM-ST system is derived from the space time code idea based on IDMA systems, which has the advantages of easily receiving, low decoding complexity and high system throughput and so on. The paper introduces the basic principles and algorithm flow of the multi-layer iterative division multiplexing space-time codes and forecasts its＇ development prospects.
