  • Abstract
    In an uplink cable modem, it is crucial to employ a preamble pattern suitable for frame acquisition, channel estimation and coarse timing/frequency acquisition. Proposed is an oversampled constant envelope zero autocorrelation code (CAZAC) for an uplink cable modem compliant with the data over cable service interface specification. The false alarm and missing probability of the proposed preamble pattern are investigated and compared to those of the existing preamble pattern based on the extended CAZAC sequence.
