In this paper we consider a general asynchronous frequencyselective multi-user CDMA system with two transmit and r receive antennae, where the information data stream (an MPSK process with energy 1/2) is space-time encoded according to Tarokh’s differential rule [1]: each user is assigned one and the same code to be used on all of the transmit antennae. Sufficient conditions for fully blind detection are established and several detection strategies are presented.

Abstract
In this paper we consider a general asynchronous frequencyselective multi-user CDMA system with two transmit and r receive antennae, where the information data stream (an MPSK process with energy 1/2) is space-time encoded according to Tarokh’s differential rule [1]: each user is assigned one and the same code to be used on all of the transmit antennae. Sufficient conditions for fully blind detection are established and several detection strategies are presented.File in questo prodotto:
