Chipset of MTD decoder in PLIS Xilinx V.V.Zolotarev. MTD_PLIS_Xilinx

Рис. 1. Многопороговый декодер сверточного СОК с R=1/2, d=5 и nA=14 This is convolutional MTD with R=1/2, d=5, 3 iterations V.V.Zolotarev. MTD_PLIS_Xilinx

Plosibilities of MTD in PLISXilinx • 1. Decoding speeds 160 - 480 Mbit/s ( and else more - in the nearest future) • 2. Code gain G~7,5 -9 dB and more - just now! • 3. Code rates R=1/4 - 5/6 - arbitrary - for all kinds of signals. • 4. The net cost will quickly diminish from $30’000 (development!) up to $300 - $1000 for middle and little series V.V.Zolotarev.
