| Abstract(in English) | We present a theory to analyze the performance of a multistage code-division multiple-access (GDMA) multiuser detector, applied to a randomly-spread, fully-synchronous baseband uncoded CDMA channel model with additive white Gaussian noise under perfect power control in the large-system limit. One of the authors, Tanaka, applied the statistical-mechanical method, replica theory, to derive We formulate the multistage detector as an approximation to the sum-product algorithm for the detection problem. We then apply the density evolution idea to analyze its detection dynamics. |
