The Advanced Extremely High Frequency (AEHF) TCC Decoder Core implements the Turbo convolutional code iterative decoding required for all AEHF SATCOM terminals, including SMART-T, SCAMP, FAB-T, NESP and all future AEHF compatible terminals.
主要機能
- Supports all required interleaver block sizes.
- Dynamic block-size switching without interruption supports multiple channels.
- Provides early termination option for reduced power consumption.
- Performs parallel processing with 8 SISOs to achieve high throughput.
- Programmable number of iterations dynamically changeable per block.
- Uses MAX-LOG-MAP algorithm with extrinsic scaling
- Achieves 50 Mbps decoded data rate with 10 iterations (135 MHz clock rate).
- Fully synchronous design with single-clock domain.
- Double-buffered input accommodates burst or continuous data.
- VHDL source code provided with self-checking test bench
