Requirements

• ISE 6.1.02i or later

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.

Key Features

• 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.
