ABSTRACT:
A system and method for signal channel balancing through accurate estimation of signal amplitude and phase parameters are described. The system includes multiple analog-to-digital (A/D) converter devices coupled to a digital signal processing (DSP) unit, each A/D converter device corresponding to a communication channel within the system. The system further includes multiple analog multiplexers, each analog multiplexer being coupled to a corresponding A/D converter device and having a number of inputs equal to the number of communication channels to be balanced within the system. The system further includes a timing generator circuit and selection logic coupled to the DSP unit, such that for each clock cycle, a single analog channel input is routed to each A/D converter device.
