Abstract

A common problem with the existing blind multi-user CDMA detectors is that their performance is very sensitive to the Signature Waveform Mismatch (SWM) caused by channel distortion. In this paper we consider the problem of designing a blind multi-user CDMA detector which is robust to the SWM. We present a convex formulation for this problem by using the Second Order Cone (SOC) programming. We also propose the use of recently developed interior point methods to efficiently solve the resulting SOC problem. Computer simulations indicate that the performance of our new robust blind multi-user detector is superior.
