The performance of multi-user cooperative diversity in an asynchronous CDMA uplink
Abstract--This paper investigates the impact of interuser non-orthogonality and asynchronous communication on the information-outage probability performance of multi-user decode-an...

A Low-Complexity Detector for Large MIMO Systems and Multicarrier CDMA Systems
We consider large MIMO systems, where by `large' we mean number of transmit and receive antennas of the order of tens to hundreds. Such large MIMO systems will be of immense i...

Asynchronous CDMA systems with random spreading-part I: fundamental limits
Spectral efficiency for asynchronous code division multiple access (CDMA) with random spreading is calculated in the large system limit. We allow for arbitrary chip waveforms and ...

Multiuser Detection of Sparsely Spread CDMA
Code-division multiple access (CDMA) is the basis of a family of advanced air interfaces in current and future generation networks. The benefits promised by CDMA have not been full...
