| 摘 要： | 针对突发信号的盲接收，提出一种快速收敛的盲均衡算法. 该算法将自适应滤波领域中的仿射投影和数据重用思想引入修正常模算法(MCMA)盲均衡器. 与传统的MCMA算法相比，大大提高了算法的收敛速率，适用于突发信号的盲均衡. 在数值模拟中，与传统的MCMA 算法在收敛速率、稳态误差等方面进行了对比分析.

| Abstract: | A novel blind equalization algorithm with rapid convergence rate is proposed to receive the burst-mode signal. The idea of affine projection and data-reusing in adaptive filtering field is applied to the modified constant modulus algorithm (MCMA). Compared with the basic MCMA, the proposed method converges faster due to affine projection and data-reusing. Derivation of the algorithm is given and its performance analyzed. In the numerical simulation, the proposed algorithm is compared with the basic MCMA in terms of convergence rate and stationary error. |
