Firstly, a simple closed-form MIMO channel capacity formula is derived by using the eigenvalue distribution of Wishart matrix.

首先，利用Wishart矩阵的特征值分布，导出了一个简单闭合的MIMO信道容量公式；然后基于此公式，得到了MIMO信道容量在高信噪比时的渐近界，解析地反映了随着信噪比的逐渐增加，MIMO信道容量与信噪比和收发天线数目的最小值呈渐近的线性关系；最后，计算机仿真验证了所提出的MIMO信道容量公式及其渐近界的正确性。

The results of simulation experiments for single channel data or arbitrary channel of multi-channel data show the clearer event, the better wave shape and the higher SNR compared with the conventional convolution filter and common SVR based on RBF.

On the one hand, de noising of instantaneous parameters is optimized by a wavelet filter, which can improve the recognition ability under the low SNR; on the other hand, the existing three feature parameters σ,σ(subscript ∞) and σ are used, and three new parameters Ra, Rp and Rf are proposed based on the existing feature parameters, which can simplify the process and improve the recognition ability.

该算法一方面提出采用小波滤波器对信号的瞬时信息进行消噪处理，提高了调制识别算法在低信噪比下的识别能力；另一方面利用已有算法的3个特征参数σ、σ、和σ以及在已有算法基础上改进的3个新的特征参数Ra、Rp和Rf，简化了识别过程，改善了低信噪比下的识别效果。
