Initial code acquisition in the cooperative Non-Coherent MIMO DS-CDMA downlink
Initial code acquisition in the cooperative Non-Coherent MIMO DS-CDMA downlink
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. The probabilities of correct detection and false alarm have been derived analytically. Furthermore, a Mean Acquisition Time (MAT) formula is provided for the cooperative transmission scenario considered. The associated MAT performance trends are characterised as a function of both the number of Relay Stations (RSs), as well as that of the receive antennas and link imbalance. As opposed to the classic scenario of having co-located MIMO elements, our findings suggest that employing distributed MIMO elements acting as RSs combined with multiple receive antennas leads to an improved MAT performance.

Abstract
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. The probabilities of correct detection and false alarm have been derived analytically. Furthermore, a Mean Acquisition Time (MAT) formula is provided for the cooperative transmission scenario considered. The associated MAT performance trends are characterised as a function of both the number of Relay Stations (RSs), as well as that of the receive antennas and link imbalance. As opposed to the classic scenario of having co-located MIMO elements, our findings suggest that employing distributed MIMO elements acting as RSs combined with multiple receive antennas leads to an improved MAT performance.
