- Abstract
- In this paper, we propose a preamble structure and appropriate acquisition algorithms for the uplink cable modem. The proposed preamble consists of a serial concatenation of identical constant amplitude zero autocorrelation (CAZAC) sequences. The proposed preamble is used for the frame detection, coarse symbol timing and carrier frequency recovery for the uplink cable modem compliant to data-over-cable service interface specification (DOCSIS) 2.0. The performance of the synchronization algorithms exploiting the proposed preamble structure is evaluated with various computer simulations.
