Patent ID: 7936808

Claim:
A method for processing signals in a communication system, the method comprising: maximizing a function J corresponding to a metric in a multiuser system with finite-rate feedback, wherein said function J generates a sum over a range n=1 to N of a product of μ n and p n , where n corresponds to a current quantization level, μ n is a conditional mean corresponding to said metric and p n is a probability that one of a plurality of receivers in said multiuser system comprises a signal-to-noise ratio (SNR) that is in an n th quantization interval [x n−1 , x n ], where x n−1 is a first partitioning threshold for said n th quantization interval, and x n−1 is a second partitioning threshold for said n th quantization interval; and determining quantization levels to be utilized by a quantizer in said multiuser system with finite-rate feedback based on said maximized function J.
