Linear multiuser detectors for synchronous code-division multiple-access channels
R. Lupas,Sergio Verdu +1 more
TL;DR: Under the assumptions of symbol-synchronous transmissions and white Gaussian noise, the authors analyze the detection mechanism at the receiver, comparing different detectors by their bit error rates in the low-background-noise region and by their worst-case behavior in a near-far environment.
Journal Article
Near-far resistance of multiuser detectors in asynchronous channels
R. Lupas,Sergio Verdu +1 more
TL;DR: In this paper, the authors consider an asynchronous code-division multiple access (CDMA) environment where the receiver has knowledge of the signature waveforms of all the users and compare detectors by their worst case bit error rate in a low background noise near-far environment.
Journal ArticleDOI
Near-far resistance of multiuser detectors in asynchronous channels
R. Lupas,Sergio Verdu +1 more
TL;DR: The authors explore suboptimal demodulation schemes which exhibit a low order of complexity while not exhibiting the impairment of the conventional single-user detector, and show that there exists a linear detector whose bit-error-rate is independent of the energy of the interfering users.
