  • Methods and apparatus for equalization and decoding of digital communications channels using antenna diversity
    Patent number: 5862192
    Abstract: An equalizer/decoder for a communication channel presenting impairments to error-free reception of transmitted symbols includes a modified Viterbi decoder operating on samples of received signals in a plurality of equivalent subchannels. Estimates of each of the subchannels are updated using a locally best estimate in the Viterbi trellis processing, thereby avoiding delay in updating channel estimates in a rapidly changing channel such as a digital cellular communications channels. A leaky predictor channel updating technique also proves advantageous in an alternative embodiment.
    Type: Grant
    Filed: December 28, 1995
    Date of Patent: January 19, 1999
    Assignee: Lucent Technologies Inc.
    Inventors: Stephen Russell Huszar, Nambirajan Seshadri
