BLIND SEQUENCE ESTIMATION

Estimating the data sequence from the received signal without knowing the transmission channel is referred to as blind sequence estimation. A new blind sequence estimation scheme is proposed by exploiting the s econd order statistical properties of the source and the algebraic str uctures of the data sequence. An optimal source (deterministic) correl ation estimator and the Viterbi algorithm are used to achieve blind se quence estimation. The proposed approach also has a special structure particularly attractive for time varying channels.
