Latest Patents

One of his latest patents is titled "Monitoring line conditions in the data transmission mode." This invention describes a method and apparatus that allows a modem transmitting data to initiate retraining mode due to changing line conditions. The modem inserts a test signal within the data received from a computer system. The data and test signal are encoded and sent over a network to a second modem. The second modem compares the test signal with a standard test signal, and if the test signal received is different from the standard test signal, the second modem initiates retraining of the modems to adjust for the varying line conditions.

Another significant patent is "MLSE implementation using a general purpose DSP and shared hardware for a GSM application." This invention involves a digital signal processor (DSP), hardware module, and shared memory that work together to perform Viterbi decoding on a sequence of received symbols. Given channel coefficients, the DSP calculates initial data for Viterbi processing, including combination values for each possible state and branch product values for each possible symbol. These values are stored in shared memory for access by the hardware module. The DSP further calculates the first few stages of the Viterbi processing so that path metrics are well defined for every state. Path metric values are also stored in the shared memory. The hardware module is optimized to perform calculations associated with a single stage of the Viterbi algorithm.
