Abstract
A method is provided for multi-channel analog-to-digital conversion. The method includes: receiving an input vector which represents a plurality of analog signals; transforming the input vector using a linear transformation matrix; converting the transformed input vector to a digital stream using an array of sigma-delta converter; and adapting the linear transform matrix to maximize de-correlation between the signals represented in the input vector.
