Preamble Design and Coarse Synchronization Using CAZAC Sequence for Uplink Cable Modem
نویسندگان
چکیده
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.

A Novel Compact Preamble Structure for Timing Synchronization in MIMO- OFDM Systems Using CAZAC Sequences
To increase the throughput of transmission systems, MIMO-OFDM technology allows for a better reach and rate of transmission and improves the reception. The synchronization between the transmitter and the receiver has become a big challenge. A bad timing synchronization causes the loss of a lot of information in a MIMO-OFDM system. In this paper, we propose a novel compact preamble structure bas...
متن کاملZadoff-Chu sequence design for random access initial uplink synchronization
The autocorrelation of a Zadoff-Chu (ZC) sequence with a non-zero cyclically shifted version of itself is zero. Due to the interesting property, ZC sequences are widely used in the LTE air interface in the primary synchronization signal (PSS), random access preamble (PRACH), uplink control channel (PUCCH) etc. However, this interesting property of ZC sequence is not useful in the random access ...
متن کاملA Low Power Preamble Detection Methodology for Packet Based Modems
In order to achieve frame synchronization in packetbased communication systems, a known sequence (preamble) is sent at the beginning of each packet. This paper presents a low power scheme for preamble detection using dynamic precision configuration. The proposed scheme is based on the observation that signal processing algorithms at the front end (including mixer, Square root raised cosine (SRR...
متن کاملBurst frame and frequency synchronization with a sandwich preamble
Preamble schemes with periodic signal repetitions are often used for synchronization purposes in transmission over dispersive media. We describe a sandamble, being a splitted repetition preamble with reduced training overhead, and compare its frame and frequency synchronization performance in burst transmission to the performance of a conventional repetition preamble like standardized for IEEE ...
متن کاملTiming Synchronization Performance of Short Preamble Sequence with Orthogonal Frequency Multiplexed Data Symbols
Wireless communications for the control of industrial equipments need to send a large amount of short packets frequently and to improve frame efficiency. The OFDM frame of wireless local area networks has short preambles that are used for timing synchronization and coarse frequency offset estimation. As the short preambles are repeated in a time domain, they occupies subcarriers intermittently....
