Abstract
In a multi-channel receiver system embodying the invention, a "trained" receiver channel which is active and propagating data signals may be used to train any other receiver channel. Each receiver channel of the system has an input and an output, with each input for receiving a different portion of an original data signal. Each receiver channel includes adaptive filter coupled between its input and its output for propagating the signals received at its input to its output. In accordance with the invention, a first trained receiver channel is used to train a second receiver channel by coupling the output of the first receiver channel to the output of the second receiver channel for training the adaptive filter of the second receiver channel. The training of the second receiver is completed by transmitting the same data signal to the first and second receiver channels.
