Latest Patents

One of his latest patents is titled "Soft Decision Enhancement." This invention involves a Viterbi trellis processing technique where both soft and hard decisions are derived from a received signal. The soft decisions are enhanced by modifying them using the hard decisions. A log likelihood ratio for a bit of the received signal can be derived by grouping candidate metrics associated with the decision that the bit has a first state and those associated with the second state. The process includes applying respective functions to these groups and calculating the difference of the function values.

Another significant patent is the "Receiver Architecture." This invention describes a wireless receiver that utilizes a joint detection Viterbi (JDV) algorithm to demodulate a signal containing both a desired signal component and an interference signal component. The desired signal includes a training sequence and at least one data field. The JDV algorithm demodulates the training sequence along with a corresponding portion of the interference signal to evaluate possible transmitted sequences and generate channel estimations for both components. The data field is then demodulated using these channel estimations as initial estimates for the JDV algorithm.
