Bill, >>>Since off-hook conditions and power cutback lower reach and performance, solution providers are considering ways to extend the reach of G.lite through better spectrum utilization (echo cancellation), improved equalization techniques, and coding gain algorithms such as Reed-Solomon forward error correction and trellis encoding. That article you posted ties together and confirms a lot of important things. Since extended reach means everything to the Telcos, the only way for G.Lite to achieve this is to employ or work around some of the patents I list below. These patents work in conjunction with one other. (guess who owns them). The first patent is echo cancellation and the second and third are clipping/quantization algorithms, all used before the D/A converter. The last one, Oversampling Techniques would also be a helper to continue raising the SNR of the transmitted signals. I found nothing on Forward Error correction patents at least for Amati. Method and apparatus for echo cancellation with discrete multitone modulation patents.ibm.com (granted May 1994 - The Board of Trustees of the Leland Stanford, Junior University, Stanford, CA (John Cioffi's patent) Mitigating clipping and quantization effects in digital transmission Systems patents.ibm.com patents.ibm.com (granted April 97 to Amati -two different techniques). patents.ibm.com (granted May 1998 to Amati - Hell, patents still coming in even after the buyout! BTW-This is an oversampling technique that improves signal-to-quantization noise ratio). It seems Amati patented everything but the kitchen sink: 1)Efficient address generation for convolutional interleaving using a minimal amount of memory 2)Method and apparatus for randomized oversampling 3)Low power parallel multiplier for complex numbers 4)Time division duplexed high speed data transmission system and method 5)ADSL compatible discrete multi-tone apparatus 6)Methods for coordinating upstream discrete multi-tone data transmissions 7)Frame synchronization in multicarrier transmission systems 8)Discrete multi-tone data transmission system using an overhead bus for synchronizing multiple remote units 10)Multicarrier modulation transmission system with variable delay Method and apparatus for establishing communication in a multi-tone data transmission system 11)ADSL compatible discrete multi-tone apparatus for mitigation of T1 noise 12)Updating of bit allocations in a multicarrier modulation transmission system ***It is now my general feeling Awre is going to be spreading some of that G.Lite licensing money around to other places. The same thing said for their Full-Rate system also.
