The Binary Core DVB-T2 modulator bc006 – compliant with ETSI TR 302 755 V1.3.1 standard – is already available for different FPGA supports. The core is area-efficient and modular, thus making tailoring to your specific requirements straightforward. MFN mode with a single Transport Stream input can be used in the stand-alone version. SFN multi-PLP mode with T2-MI input is supported if Binary Core bc006 core is used along with an external DVB-T2 gateway (also available from Binary Core on
request). Upgraded for T2-lite transmission.
DVB-T2 Modulator IP Core
Overview
Key Features
- Bandwidth agility 1.7 MHz, 5 MHz, 6 MHz, 7 MHz, 8 MHz, or 10 MHz.
- MultiPLP support with T2-MI stream generated by external DVB-T2 Gateway.
- Single Frequency Network (SFN) transmission mode (relative, absolute) supported with T2-MI stream generated by external DVB-T2 Gateway.
- T2-lite support (T2-base + T2-lite configuration are managed by a single modulator core).
- FFT sizes: 1K, 2K, 4K, 8K, 8K extended, 16K, 16K extended, 32K, 32K extended.
- Guard interval fractions: 1/128, 1/32, 1/16, 19/256, 1/8, 19/128, 1/4.
- Scattered pilot patterns: 8 different versions (PP1... PP8) matched to guard intervals.
- Continual pilots with improved optimization to reduce overhead, with respect to DVBT.
- Supported code rates: 1/2, 1/3, 2/5, 3/5, 2/3, 3/4, 4/5 and 5/6 with normal and short FECFRAME. Additional supported code rates for T2-lite: 1/3, 2/5 with short FECFRAME.
- Data and L1post signalling scrambling.
- L1-ACE offset correction and P2 bias balancing cells insertion.
- Supported modulation format: QPSK, 16QAM, 64QAM and 256QAM.
- Rotated constellations, which provide a form of modulation diversity, to assist in the reception of higher coderate signals in adverse channel condition.
- Extended interleaving, including bit, cell, time and frequency interleavers.
- Frame structure with special (short) identification symbol, for rapid channel scanning, signal acquisition, and framestructure parameters transmission.
- Multiple Input Single Output (MISO) using the Alamouti technique.
- T2-MI interface support (Baseband data frames, L1 signalling frames, P2 bias balancing frames, DVB-T2 timestamp frames, FEF frames).
- Selective digital filter for shoulder attenuation.
- Matching to DAC clock frequency, thanks to a Numerically Controlled Resampler (NCR).
- Configurable pre-IFFT linear prefiltering.
- [optional] Externally configurable non linear predistortion.
- [optional] Adaptive non linear predistortion using a post RF amplifier feedback signal.
- [optional] TS extraction from IP with SMPTE 2022-1/2.
