The Advanced Extremely High Frequency (AEHF) TCC Encoder Core implements the Turbo convolutional code encoding required for all AEHF SATCOM terminals, including SMART-T, SCAMP, FAB-T, NESP and all future AEHF compatible terminals. The code is a rate 1/2 parallel concatenated TCC with 8-state duo-binary constituent encoders and supports all required interleaver sizes.
主要機能
- Supports all required interleaver block sizes.
- Dynamic block-size switching without interruption supports multiple channels.
- Input FIFO (18 Kb) supports burst or continuous data.
- Achieves 200 Mbps coded data rate (200 MHz clock rate).
- Low latency of 14 clocks independent of block size.
- Synchronous design with single clock domain.
- VHDL source code provided with self-checking test bench.
