摘要 随着卫星数传容量急剧增加,高阶调制解调方式在实际中被广泛采用,卫星通信系统的性能有了更高的要求。针对这一现状,给出一种基于最小均方根的相位噪声抑制算法,能够通过对相位噪声的抑制来有效地提高高阶调制解调系统误码性能。MATLAB仿真证明,改进的噪声抑制算法相比之前的基本噪声补偿算法对高阶调制解调系统的相位噪声有更好的抑制能力,能够进一步提高系统信噪比,降低系统误码率。 With the increasing capacity of remote sensing satellite data transmission, when high order modulation and demodulation is widely used, the request of the system performance is much higher. According this situation, this paper proposes an improved method to reduce phase noise. This paper improved the performance of system with reducing the affect of phase noise. Through the MATLAB simulation, the method have a better performance of reducing the phase noise and the system has better performance and lower BER.
