Asymptotic Analysis of General Multiuser Detectors in MIMO DS-CDMA Channels
Keigo Takeuchi, Toshiyuki Tanaka, Toru Yano
We analyze a MIMO DS-CDMA channel with a general multiuser detector including a nonlinear multiuser detector, using the replica method. In the many-user, limit the MIMO DS-CDMA cha…

Hierarchical Decoupling Principle of a MIMO-CDMA Channel in Asymptotic Limits
Keigo Takeuchi, Toshiyuki Tanaka
We analyze an uplink of a fast flat fading MIMO-CDMA channel in the case where the data symbol vector for each user follows an arbitrary distribution. The spectral efficiency of th…
