5 5 Plosibilities of MTD in PLIS Xilinx 1. Decoding speeds Mbit/s ( and else more - in the nearest future) 1. Decoding speeds Mbit/s ( and else more - in the nearest future) 2. Code gain G~7,5 -9 dB and more - just now! 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. 3. Code rates R=1/4 - 5/6 - arbitrary - for all kinds of signals. 4. The net cost will quickly diminish from $30000 (development!) up to $300 - $1000 for middle and little series 4. The net cost will quickly diminish from $30000 (development!) up to $300 - $1000 for middle and little series
