TL;DR: This paper analyzes the performance of Haar wavelet based S-CDMA (HW/S- CDMA) over a synchronous additive white Gaussian noise (AWGN) channel using a decorrelating multi-user detector and results reveal that HW/s-CDma holds promise since the users of HW/S -CDMA can achieve variable and higher data rates than those of direct sequence (DS)-CDMA.

Performance of quasisynchronous scale time code division multiple access for AWGN channel
Ferkan Yilmaz,Oguz Kucur +1 more
TL;DR: This work analyzes bit error rate performance of a recently proposed multiple access system called scale time code division multiple access (STCDMA) for quasisynchronous communication over an AWGN channel and shows that the performance of STCDMA gets much better than that of CDMA over the quasis asynchronous AW GN channel as the number of scales increases.

TL;DR: The two new multiple access systems are Scale-Time-Code Division Multiple Access (STCDMA) and Scale- code Division Multiple access (SCDMA), where STCDMA is user-advantageous and SCDMA is information- advantageous.

TL;DR: This paper presents a survey of recent results and provides several new results on the periodic and aperiodic crosscorrelation functions for pairs of m-sequences and for Pair of related (but not maximal-length) binary shift register sequences.

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.
