“…OFDM Waveform Generation, adapted from [7], [8] and [9] of the access network or 'last mile' in Internet Infrastructure, the PSTN (Public Switched Telephone Network) network and the walled-garden TV networks, or others underlay networks, enable the access from end-users to the Internet. The ADSL (Asymmetric Digital Subscriber Line) technology was spread over the PSTN network, the DOCSIS (Data Over Cable Service Interface Specification) 3.0 protocol [17] did the same thing in a HFC network, as well as the GPON (Gigabit-capable Passive Optical Network) [18] in FTTh network. Hence, it was no suprise that local area networks, such as the IEEE 802.11 Standards Body [19], and the latest cellular generation released in 2011, the LTE Advanced [20], made possible the final convergence of all networks over IP-based technologies, known as broadband networks.…”

This paper addresses the main two types of video delivery networks deployed into digital television services throughout the years. Underlying and Overlay networks are described in order to introduce how the physical infrastructure and network architecture impacted on the modeling of the latest video content delivery schemes. The convergence of different video delivery networks, in a technical sense, is a real thing and may disrupt the broadcasting industry in the long-term.

“…The pilot pattern of 8K-FFT mode has almost the same SP pattern allocation as 4K-FFT mode except that pilots are stepped by two subcarriers from one OFDM symbol to the next [1]. By inserting SP subcarriers with 2 subcarriers span, the SPs of 8K-FFT do not cover all subcarrier locations.…”

“…DOCSIS 3.1 DS(downstream) can be applied to increase the data rate of cable network comparable to the fiber network with 10Gbps [1]. DOCSIS 3.1 has high flexibility in allocating PLC(physical layer-link channel) which transmits OFDM parameters and downstream profile information [2].…”

Abstract:In this paper, we propose an integer frequency offset estimation and compensation method based on PLC preamble correlation in DOCSIS 3.1 Downstream system. The proposed method determines the PLC preamble subcarrier location recovered from PLC data and the one obtained from PLC preamble correlation. We showed the performance of PLC preamble detection in the received signal through the maximum value detection of PLC preamble correlation. Thus we can estimate and compensate for the integer frequency offset by computing the difference of PLC subcarrier locations.

“…Various optical and wireless access technologies have been investigated, including passive optical networks (PON) [1][2][3], cloud-radio access networks (C-RAN) [4][5][6][7], and hybrid fiber coax (HFC) networks [8,9]. In the United States, there are more than 50 million subscribers using cable services for broadband access, which is 40% more than digital subscriber line (DSL) and fiber-to-the-home (FTTH) users [10]. Given the emergence of data over cable service interface specification (DOCSIS)…”

We first demonstrate delta-sigma digitization and coherent transmission of data over cable system interface specification (DOCSIS) 3.1 signals in a hybrid fiber coax (HFC) network. Twenty 192-MHz DOCSIS 3.1 channels with modulation up to 16384QAM are digitized by a low-pass cascade resonator feedback (CRFB) delta-sigma analog-to-digital converter (ADC) and transmitted over 80 km fiber using coherent single-λ 128-Gb/s dual-polarization (DP)-QPSK and 256-Gb/s DP-16QAM optical links. Both one-bit and two-bit delta-sigma digitization are implemented and supported by the QPSK and 16QAM coherent transmission systems, respectively. To facilitate its practical application in access networks, the coherent system is built using a low-cost narrowband optical modulator and RF amplifiers. Modulation error ratio (MER) larger than 50 dB is successfully demonstrated for all 20 DOCSIS 3.1 channels, and high order modulation up to 16384QAM is delivered over fiber for the first time in HFC networks. The raw DOCSIS data capacity is 54 Gb/s with net user information ~45 Gb/s. Moreover, the bit error ratio (BER) tolerance is evaluated by measuring the MER performance as BER increases. Negligible MER degradation is observed for BER up to 1.5 × 10 −6 and 1.7 × 10 −4 , for one-bit and two-bit digitization, respectively.
