Kurzfassung deutsch:
The standard Approximate Message Passing (AMP) algorithm optionally considers i.i.d. measurement noise. The governing parameter is the noise variance. When the noise is independent, but not identically distributed, applying AMP with the noise variance parameter set to the average of the actual noise variance results in significantly degraded performance. We propose a modified AMP algorithm called AMP-VN which
improves performance for known noise variances.
