Fractionally spaced linear joint detection for multitone CDMA systems

We consider a fractionally spaced linear joint detector for multitone CDMA systems. We first derive the structure of the receiver for an MMSE criterion. Then we exactly evaluate the BER achieved by this detector for BPSK modulation in steady-state conditions. We consider an asynchronous scenario whe...

Description
Summary:We consider a fractionally spaced linear joint detector for multitone CDMA systems. We first derive the structure of the receiver for an MMSE criterion. Then we exactly evaluate the BER achieved by this detector for BPSK modulation in steady-state conditions. We consider an asynchronous scenario where the signal of each user propagates over a two-path channel. The resistance against a near-far scenario is also demonstrated.
