Abstract: In this paper we investigate a chip rate implementation of the MMSE multiuser receiver in the case of uplink UMTS context where data are scrambled by long codes (Gold sequences). The main problem is the resolution of a high dimension linear system involving a band-diagonal auto-correlation matrix. Using a Cholesky (or LDU) decomposition and taking advantage of the multiuser correlation expression, we show that the complexity of this chip rate MMSE is similar to that of the more classical symbol ...
