摘要 在现代无线通信系统中,采用正交空时分组码(STBC)的多天线发射技术是提高通信速率和可靠性,并且能够实现简单译码的关键技术。该文针对瑞利信道系统模型,提出一种适用于多入单出正交空时分组码(OSTBC)的调制识别算法。该算法通过对接收到的数据进行重排,将多入单出的系统模型转化为类似多入多出的系统模型,并且根据信源的特殊性用最大似然的思想实现调制类型的识别。仿真结果验证了所提算法的有效性。 In modern wireless communication systems, multiple-antenna-transmitting in association with Orthogonal Space-Time Block Code（OSTBC） is a key technology to improve communication rate, reliability, and decoding complexity. In this paper, a modulation identification algorithm is proposed which is well suitable for the Multiple Input Single Output（MISO）-OSTBC system. First, the MISO system is transformed into a Multiple Input Multiple Output（MIMO） system by reshaping the received data. Then, maximum likelihood based approach is used to identify the modulation. Simulations validate the effectiveness of the proposed algorithm.
