Initial code acquisition in the cooperative Non-Coherent MIMO DS-CDMA downlink
, 2009 In this paper we investigate a realistic code acquisition assisted cooperative Non-Coherent (NC) Multiple-Input Multiple-Output (MIMO) DS-CDMA downlink scenario, when communicating over uncorrelated single-path and multi-path Rayleigh channels.

A Novel Packet Scheduling Scheme for Downlink LTE System [PDF]
, 2013 Long term evolution (LTE) is the next generation wireless system. There are not many researches for LTE downlink scheduling. It uses orthogonal frequency division multiple access (OFDMA) in downlink. Until now, the goal for the LTE scheduler is achieving

Differentially Coherent Code Acquisition in the MIMO-Aided Multi-Carrier DS-CDMA Downlink
, 2007 Both differentially coherent and non-coherent code acquisition schemes designed for the multiple-input multiple-output (MIMO)-aided multi-carrier (MC)-DS-CDMA downlink are analysed, when communicating over uncorrelated Rayleigh channels.
