نویسندگان
چکیده
In this paper, a low complexity long pseudo noise (PN) code acquisition scheme is proposed for spread spectrum systems including global positioning system (GPS) and code division multiple access (CDMA) system. By using a phaseshift-network, the proposed scheme has less complexity than the conventional dual correlating sequential estimation scheme. From the analytic and numerical results, it is confirmed that the proposed scheme has the lower hardware complexity and the same mean acquisition time performance compared with the conventional scheme.

Improving Long PN-Code Acquisition in the Presence of Doppler Frequency Shifts
Wireless communication is the major form of connection nowadays. In most cases it exploits the benefits of the spread spectrum techniques to overcome channel introduced corruptions like Doppler residual frequency, noise, interference and jamming. These techniques also enhance the security and quality of the link. Using long spreading pseudo-noise codes provides further security for the link tho...
متن کاملRapid Acquisition of Pn Signals for Ds/ss Systems Employing a Phase Estimator
We propose a scheme for rapid acquisition of PN signals for direct-sequence spread spectrum (DS/SS) CDMA systems by estimating the phase of the incoming PN signal with the use of an auxiliary signal. The phase of the incoming P N signal is estimated using the cross-correlation properties between the PN signal and the auxiliary signal. The estimated phase is used to initialize the phase of the l...

Recently, the smart antenna (a blind adaptive antenna array) has brought much attention to its ability to improve the future code-division multiple-access (CDMA) wireless communications systems. However, Adachi et al. [1], [2] employed only one out of elements that are in a smart antenna array during the pseudonoise (PN) code acquisition process due to the difficulty in obtaining the weight coe...
متن کاملCombined Scheme for Fast PN Code Acquisition
In direct-sequence wideband (DS-WB) systems, long spreading sequences are used to span multiple symbol intervals in order to remove spectral lines and to mitigate multiple access interference. The usage of long spreading sequences will result in a large search space during acquisition stage. As a result, the DS-WB systems will need a lot of time to achieve acquisition state. This paper proposes...
متن کاملAcquisition Time Analysis of Non - Coherent Pn Sequence Acquisition Schemes
In direct-sequence spread-spectrum systems, successful communications require phase synchronization of the incoming pseudonoise (PN) coded waveform with a locally generated replica at the receiver. It has been previously shown that sequential PN code acquisition schemes have the potential to achieve the best performance, but they are the least analyzed because of the analytical difficulties. Th...
