| description | The invention provides a binaural beam forming optimization algorithm based on a convex optimization relaxation technology. The method comprises the following steps: receiving a binaural beam signal; and a relaxed binaural beam forming optimization model is adopted to optimize a binaural beam signal. The invention provides a more efficient optimization algorithm, so that the solution quality is higher; and noise reduction and binaural cue protection can be realized at the same time under the condition of relatively low calculation complexity.
本发明提供一种基于凸优化松弛技术的双耳波束形成优化算法，该方法包括：接收双耳波束信号；采用松弛双耳波束形成优化模型优化双耳波束信号。本发明提出一种更高效的优化算法，能使得解质量更高；并且在较低计算复杂度条件下，能够同时实现降噪和双耳线索保护。 |
