Abstract
A one-shot linear decorrelating detector (LDD) for the detection of asynchronous CDMA is presented. By treating every user as two independent users and using maximal ratio combining, a bit-by-bit detection is obtained. By applying a phase estimation algorithm on the output of the one-shot LDD, it is shown that the proposed detector can be used for the detection of asynchronous CDMA without the knowledge of carrier phase of any user. Simulation results show that the performance of the proposed detector approaches that of the optimum detector for single user transmission.
