ABSTRACT:
An apparatus and method for decorrelating pairs of mutually contaminated channels in a multi-channel digital signal including two identical data processing paths and a feedback path. Each pair of mutually contaminated channels consists of a first contaminated channel and a second contaminated channel. Initially, first and second shined signals are generated by shifting the original contaminated signal such that the first shined signal has the first contaminated channel centered at zero frequency and the second shined signal has the second contaminated channel centered at zero frequency. Each of the first and second shifted signals are coupled to one of the two identical signal processing paths. The first path generates an error corruption component corresponding to the first shifted input signal and subtracts this corruption component from the second shifted signal in order to generate a third decorrelated digital signal. The second path generates an error corruption component corresponding to the second shined input signal and subtracts it from the first shifted signal in order to generate a fourth decorrelated digital signal. The feedback path generates a current average error correlation factor by multiplying the third and fourth to generate an instantaneous error factor and summing this with the previous average error correlation factor for all samples. The current average error correlation factor is used to generate the first and second error corruption components. Each of the corrupted channels in the original contaminated digital signal are decorrelated when the third and rough digital signals are decorrelated.
