The S-Band Receiver Chipset is a fully standard compliant DVB-SH Demodulator. DVB-SH is a standard for a hybrid digital broadcasting system, composed of a Satellite Component (SC) and a Complementary Ground Component (CGC).
There are three main characteristics of the DVB-SH standard that make the S-band Receiver chipset a very attractive product:
The primary goal of the S-Band Receiver Chipset project is the development of a fully standard compliant DVB-SH Demodulator and the DT4500, a test signal generator for all configurations available in the DVB-SH standard.
The DVB-SH demodulator IP has been optimized for best user experience in mobile scenarios. It can be mapped to virtually any ASIC or FPGA technology. The configurable and flexible architecture enables an optimal trade-off between complexity and functionality depending on the use-case.
The DT4500 DVB-SH Signal Generator is a test signal generator for the full DVB-SH standard. It features live physical layer encoding for two TDM and one OFDM path using MPEG-TS files as an input. An integrated 18-tap multipath channel emulator is available on the OFDM path. Stationary or time variant flat fading can be applied to all paths. Noise generators can individually be configured for each of the RF outputs.
The key issues being addressed are:
The main benefits of the DVB-SH Demodulator IP to be developed in this project are listed below.
To cope with the multitude of possible system configurations the DVB-SH Demodulator developed in this project offers a flexible, configurable, and extensible soft IP capable to support the full range of DVB-SH system configurations and waveform parameters.
The key features are:
Being a soft IP designed for maximum flexibility and performance, the customer can tailor the IP for a variety of application scenarios:
The project is split into two phases. Specifications are elaborated in Phase 1, while design and implementation is carried out in Phase 2.
Phase 1 “System Specification” is concerned with the following tasks:
Phase 2 “Implementation” comprises of:
Two target platforms were used for development and validation of the DVB-SH Demodulator IP.
The project is completed.
