Performance of Parallel Code Acquisition Schemes for Multicarrier CDMA over Frequency-Selective Rayleigh Fading Channels
Performance of Parallel Code Acquisition Schemes for Multicarrier CDMA over Frequency-Selective Rayleigh Fading Channels
In this contribution we investigate the issue of pseudo-noise (PN) code acquisition in a multi-carrier CDMA (MC-CDMA) system, which is suitable for high data rate transmissions. Specially, we investigate the acquisition performance of a pure parallel acquisition scheme over frequency-selective fading channels under the multiple in-phase states ($H_1$ cells) hypothesis, considering both noncoherent equal gain combining (EGC) and selection combining (SC) of the correlator outputs associated with the sub-carriers. It is demonstrated that the acquisition performance of the MC-CDMA scheme is better than that of the equivalent single-carrier CDMA (SC-CDMA) benchmarker, when EGC is employed, and it is similar to that of the single-carrier CDMA scheme when SC is employed.

Abstract
In this contribution we investigate the issue of pseudo-noise (PN) code acquisition in a multi-carrier CDMA (MC-CDMA) system, which is suitable for high data rate transmissions. Specially, we investigate the acquisition performance of a pure parallel acquisition scheme over frequency-selective fading channels under the multiple in-phase states ($H_1$ cells) hypothesis, considering both noncoherent equal gain combining (EGC) and selection combining (SC) of the correlator outputs associated with the sub-carriers. It is demonstrated that the acquisition performance of the MC-CDMA scheme is better than that of the equivalent single-carrier CDMA (SC-CDMA) benchmarker, when EGC is employed, and it is similar to that of the single-carrier CDMA scheme when SC is employed.
