Because prior-art rate determination algorithms are prone to falsing, a sub-rate discrimination metric generator (160) is provided herein. The generator (160) correlates a received frame with known characteristics of sub-rate frames to generate additional metrics useful in rate determination. These metrics...http://www.google.de/patents/US6285682?utm_source=gb-gplus-sharePatent US6285682 - Method and apparatus for determining the frame rate of a frame
