Partially blind adaptive MMSE interference rejection in asynchronous DS/CDMA networks over frequency-selective fading channels
TL;DR: A new cyclic blind recursive least squares (RLS)-based algorithm is introduced, capable of tracking the periodically time-varying receiver structure, and allowing adaptive interference cancellation with a moderate complexity increase.
Journal ArticleDOI
Blind adaptive multiuser detection for asynchronous dual-rate DS/CDMA systems
TL;DR: An asynchronous direct-sequence code division multiple access (DS/CDMA) system wherein users are allowed to transmit their symbols at one out of two available data rates is considered, and it is shown that detection of the users transmitting at the higher rate requires a periodically time-varying processing of the observables.
Journal ArticleDOI
Time-varying narrow-band interference rejection in asynchronous multiuser DS/CDMA systems over frequency-selective fading channels
TL;DR: This paper deals with the problem of joint suppression of multiple-access interference and narrowband interference in fading, dispersive channels by introducing batch-estimation procedures to be implemented offline, which require very little and sometimes no prior knowledge as to the interference structure.
Journal ArticleDOI
Optimum detection over Rayleigh-fading, dispersive channels, with non-Gaussian noise
TL;DR: The paper discusses the problem of detecting one out of M Gaussian correlated signals in impulsive noise, modeled as a compound-Gaussian, possibly correlated process, and focuses on binary frequency-shift keying signaling, indicating that the performance depends on the energy contrast as well as on the "time-bandwidth" product of the useful signal.
Journal ArticleDOI
Code-aided blind adaptive new user detection in DS/CDMA systems with fading time-dispersive channels
S. Buzzi,A. De Maio,Marco Lops +2 more
TL;DR: This paper considers the problem of detecting the entrance of a new-user in a direct-sequence code division multiple access (DS/CDMA) system operating over a fading dispersive channel and proposes detection algorithms based on the application of the generalized-likelihood-ratio-test (GLRT).
