摘要

正交空时码(OSTCs)由于其具有充分的多样性和较低的实现复杂度，近年来引起了人们的广泛关注。在本文中，我们成功地推导了在MIMO系统中有效使用ostc的方法。计算了正交ST码的编码增益和接收机的快速ML解码可以分别解码。通过正确选择信号星座，比较不同QPSK和QAM技术的误码率(BER)和信噪比(SNR)，实现了这一目标。仿真结果表明，所得到的星座不仅优于传统的QAM星座，而且也优于其他常用的高效数据通信星座。

Orthogonal Space-Time Codes Based Signal Constellations for MIMO System

Orthogonal space-time codes (OSTCs) have recently captivated considerable attention due to their properties of full diversity and low implementation complexity. In this paper, we derive effective use OSTCs for MIMO systems successfully. It has been calculated coding gain of the orthogonal ST code and fast ML decoding at the receiver can be decoded separately. This goal achieved by properly choosing the signal constellations and compare bit-error-rate (BER) to signal-to-noise ratio (SNR) of different QPSK and QAM techniques. Simulation results show that the obtained constellations outperform not only the conventional QAM constellation, but also other well-known constellations used for efficient data communications.
