    Abstract

    An estimator for slowly varying multipath channels for each user
    in a random-code-division multiple-access communications system is
    constructed and analysed. The estimator requires no training sequence
    and we compare the performance to the case when such a sequence is
    available. We show that mean square error in estimation decreases as the
    inverse of the sample size. It is also shown that the proposed method
    performs better than other known techniques applied to equivalent
    fixed-code systems
