ABSTRACT:
The present invention provides a system and method for implementing a new TEQ training approach that trains TEQ coefficients by exploiting both time-domain and frequency-domain information. An advantage of this technique is that it reduces memory usage due to the training process. In addition, the complexity of the training process is simplified, and the associated computational work is reduced. The reduction of memory usage and computational work in turn may lead to cost savings, power consumption savings and other advantages.
