The WiMedia 1.5 LDPC Decoder IP supports all LDPC coding schemes as defined by the standard.
The WiMedia UWB standard was developed by the WiMedia Alliance. Version 1.5 of the standard introduces high payload throughputs of up to 1 Gbit/s for short range communication. LDPC codes have been adopted for these high data rate modes, while convolutional codes are used for the low data rate modes.
- Support for different code rates (1/2, 5/8, 3/4, and 4/5).
- Support for different block lengths (1200 bits and 1320 bits).
- Compliant with Multiband OFDM Physical Layer Specification, PHY Specification: Final Deliverable 1.5, August 11, 2009.
- High-throughput Applications
- Low-latency Applications
- Ultra-wideband (UWB)
- Microwave Links
- Optical Links
- TeleCare / TeleHealth
- Block-to-block on-the-fly configuration.
- Low-power and low-complexity design.
- Layered LDPC decoder architecture, for faster convergence behavior.
- Decodes more than 5 codeword bits per clock cycle for throughputs beyond 1 Gbit/s.
- Early stopping criterion for iterative LDPC decoder, saving a considerable amount of energy.
- Configurable amount of LDPC decoding iterations for trading-off throughput and error correction performance.
- Collection of statistic information (number of modified information bits, number of iterations, decoding successful).
- LDPC Encoder included.
- Available for ASIC and FPGAs (Xilinx, Altera).
- Deliverable includes VHDL source code or synthesized netlist, VHDL or SystemC testbench, and Matlab, C or C++ bit-accurate simulation model.
