Patent 7139967 was granted and assigned to Vanu on November, 2006 by the United States Patent and Trademark Office.
In one aspect the invention is a method for sequence estimating. The method includes receiving convolutional codes. The method further includes using a lazy Viterbi decoder to decode the convolutional codes. The convolutional codes may be stream convolutional codes. The convolutional codes may also be block convolutional codes. The lazy Viterbi decoder may be used in a software radio environment.
