ABSTRACT:
A method for dynamically switching hybrids during modem initialization to maximize channel capacity and performance includes the steps of evaluating each hybrid in the modem according to a cost function dependent on the quiet receive noise floor and the transmit signal echo, and then selecting the hybrid that results in the minimum value for the cost function. By performing these steps, the best available hybrid is selected in order to maximize channel capacity and hence maximize modem performance.
